Sid this chart has the same errors as the one on other site, who mever made it does not know shit about differentials. Examples 70-81 Camaro and 68-72 Checelles are 61 inches not 62,5, an axle shaft for a 67 Camaro, 67 Chevelle and a 68 Nova are the same part number and this chart shows different widths for each. 66-69 fairlane/torino are 60 not 61.25.

Bad infoRather than adding to the problem why not be a part of the solution. If you KNOW it's bad (info) then rather than an answer such as this, give the corrections needed.

You're a hoot. How about you come up with this list, huh? I don't know the exact widths but I know some of those that have different widths quoted are, in fact the same width(as markm states) there fore the list has bad info. Besides I didn't post the list. (copy and paste)

Yes Maddog ,

Instead of Slam Slam Slam , Help out, Tell me whats wrong on the List , I didn't Copy & Paste . A member here email it to me to Help me and I don't think he did it to cause BS like what is going on with the thread, Also I notice that it's a post over 4 years old . Why are you climbing on any one now ?
If you know what is wrong with it then say so !!

Maddog
09-21-2015, 06:26 AM
It's been pointed out a couple of times, there are rear ends that are listed as different widths when in fact they are the same, I'm not the rear end expert and I don't post lists so you posted it, figure it out correctly.

Pointed out Only by one person , Markm not 2 Times like you say

Like Rick said (Actually it's a much better chart than many. I see a few tiny errors, none gross.)

So unless you can help make the chart better and if you cant Please keep the shit slings to yourself .

No one slammed you or your list. Mark pointed some errors out and I said it has bad info, which it does. You're taking it personally because you posted it, I guess. You'd know it if I were slinging shit.

Maddog, that's not the way I read what you posted.


here';s what I posted:"

"Bad info"

I guess you guys can read anything into what ever you like. I don't like typing a bunch of BS on threads. I'll expand further. The list is probably 90% good, but has some glaring errors for a Chevy person, at least one that has some knowledge of Camaros, Chevelles Novas.. I would have no idea if the Ford stuff is good or not, and don't really care. I don't really care what a rear end width is as I would normally have the original in most any given car. If I was to change it would be built to fit what ever I was trying to do so I wouldn't rely on finding something stock. This whole thing is a dumb waste of time. Anyone that wants to improve that list go ahead, it won't be me.

Here's some minor corrections that I see:

Granada/Versailles is 58.50" with discs (and all the Versailles had them), Monarch should be included
Granada/Monarch is 58.25" with drums (those two could have either drums or discs)

I think the 58.00" early Bronco number is slightly off, s/b 57 something.

63.50" for 67 Fairlane is in error, more like 60". The 61.25" on another line may be the right number.

The 55-57 Chevy width is 60.25".

67-69 Camaro and 68-74 Nova are the same, not sure if they are 60" or 60.25".

For both of the above the discrepancy is probably as simple as whether you measure across the brake drums or the axle flanges. That may be the difference between what's listed for other cars vs. other lists too.

Thing is, as time goes on, finding these axles at a junkyard price is increasingly difficult. Not only that, your choices and prices on aftermarket 9" Ford or 12 bolt Chevy axle assemblies and parts have never been better. So this kind of list while useful, is not what it once was.

Thank you Rick

I will try to correct them ,
I will try to some more research and make sure they are closer than they are now.

Thanks Sid

66-69 Fairlane, Torino, cyclone, 66-70 falcon, 67-70 mustang, cougar are 60.

67-69 Camaro and 68-74 Nova are the same, not sure if they are 60" or 60.25". Add to that 64-67 Chevelle.

Coming in at 61 inches, 70-81 Camaro, 68-72 Chevelle, 70-72 Monte

As bad as the Ford / Chevy info is I am positive Mopar junk is just as bad, but I never took the time to learn it. The only reason I know Ford is from running that junk until I built up a supply of 12 Bolt/ Dana 60 stuff. Now I am gathering some 9.3 Olds stuff.

NickP

Thank you Rick I will try to correct them , I will try to some more research and make sure they are closer than they are now.Thanks SidThings to consider. When a list, regardless of the supplier or author is presented, many aspects can, as pointed out by Rick_L need to be understood. Measurements, where and how measured can impact the accuracy of the final width. Were one to want to regenerate the list it might be a good thing to clarify what a width is, i.e. bare housing, bare housing with backing plates, housing with backing plates and axles and housing with backing plates, axles and either drums or if stock with disc hat/rotor.Case in point: 1966 to 1977 Ford Bronco. I can, with some degree of knowledge tell you that the housing, bare, is in fact 53.3125" bearing flange to bearing flange. If you add the brake backing plates then you add 1/8" per side yielding a total width 53-9/16". Ford, depending upon year of manufacture and application has 4 different axle flange offsets. Here is where the differences really come to play. They are as follows - 2.00", 2.2500", 2.375" and 2.500 Each its own animal with its own specific attachments for backing plates and or disc brake units. If you're purchasing ANY rear regardless of manufacture, make certain it has ALL of the parts or one might endure unnecessary pain and anguish when trying to assemble a complete unit.So, back to the Bronco: We have a total width of 53.5625 so far. Listed, is 58. Working backwards, 58"-53.5625 = 4.4375 4-7/16/2 = 2.218 This doesn't equate to any of the axle offsets known. Enter here measurement methods and accuracy of the equipment.

I do believe that all of the dimensions in the chart are either "over the drums" or "over the axle flanges" (only a slight difference). This is the way most of these charts are done.

My thought is that this is the right way to present info on junkyard axle assemblies because people want to know whether they can use them as is for width. It's also what you can measure directly when looking at a complete axle assembly.

Not that bare housing widths aren't to be discussed, as Nick says there are other factors too.

markm
09-22-2015, 01:06 PM
I confirm my suspicions about things being the same in this manner. I ran a tape on a 68 Mustang axle assembly found it to be 60 inches overall, then looked in my Hollander interchange manuals to see what axle shafts fit that housing. If the axle shafts interchange overall width has to be identical.

I think Cnut will have some comments about the Corvette numbers when he returns. My experience is limited to C3 stuff.

chevynut
09-25-2015, 09:58 AM
Yes I thought I replied to this years ago. The C4 dimensions are all wrong. IMO these dimensions should be either to the wheel mounting surfaces or to the axle flanges, but all should be consistent. Whoever put this together obviously doesn't know how to use a tape measure, or he just assembled all of the bad info on the internet. ;)

early C4 is 62" wide

late C4 is 63 1/4" wide

Both dimensions are WITH brake rotors installed.

Thanks Cnut, one of my buddies has a pile of 8 3/4 Mopars laying on pallets any takers on betting the Mopar numbers are equally out to lunch.

This may help someone.

'57-'58 Pontiac housing dimensions 55" flange to flange (Olds is 54") - Axle length 29 1/2"



'59-'60 Pontiac housing flange to flange 59 3/16" - Axle length 31-7/8”



'61-'62 Pontiac housing flange to flange 57-7/8”



'63-'64 Pontiac housing flange to flange 59-3/16” - Axle length 31-7/8”

The '57 Pontiac and Oldsmobile housing are a direct bolt.

The driveshaft will have to have the proper yoke installed/balanced to mate to the larger 1330 U-joint.

markm
04-12-2021, 06:20 AM
The Olds/Pontiac does not use a 1330 U-joint, it uses a 2R same as late 70s GM. My 56 runs a shortened 77 Cutlass driveshaft with the Cutlass joints in it.

Rick_L
04-12-2021, 06:28 AM
It's been a really long time, but I don't think all used a 2R u-joint. Pretty sure the 3rd member in the one I had in a 55 had a Spicer, though I don't remember it being a 1330 either.

shoeboxpaul's numbers don't seem right. 55" flange to flange on the bare housing seems to high for a 57 housing, as does 59" for a later one. And I don't think that 61-62 axles were narrower than 59-61 or 63-64.

55" is pretty close to the width of a '57 rear axle bare housing (I just attempted to measure one in my garage (although the bulge in middle for the gears makes it a little difficult to get an exact measure...

This section is difficult to contribute to as the information needed is probably in the hands of PROFESSIONALS who are working with the more modern rear ends and are not afraid to light up a tourch or plug in a grinder and cut stuff up OR have actually fitted our beloved Tri 5's with a modern rear end. It may be simplier in back because the field consists of just cars,vans SUV's and the axle housing length. PROBABLY

The front is really weird yet almost any PROFESSIONAL FABRICATOR is still unwary. So us armatures are at the mercy of something more than simply Interchange Experts it seems.

yes, I looked at Mopar rears and even sent one off to Moser. They wrote back that (on the axle assembly I sent them) couldn't be made to fit because of the offset center section. New tubes were out to for some reason, probably strength or something. This was probably 15 years ago.
