I received my plate looks great!!!
Do you know what year Astro van boosters will fit? I'd liked to buy a complete used unit with MC & hoses.
Also it was already ask but does the standard MC like the CPP unit fit the Astro booster?
Thanks

Commonly used master cylinders will bolt up but you may need to modify the pushrod.
A little off topic, but how do you rig the rod from the pedal, to the hydro boost? My hd unit currently has a swivel rod with a giant eyehole on the pedal end, does this pop out?
I bought one of your plates off ebay, nice work on that, fit is awesome. Now I need to figure out linkage after I get it powder coated.
Thanks in advance, Greg.
Greg, here's what I did. I don't remember exactly how I pulled the stock pushrod out but it's "crimped" in place with a ball on the end as I recall. I think I threaded the rod and used a nut, washer and a bushing and tightened the nut to pull the pushrod out...

Thanks, that helps a lot, like the old saying, a picture is worth a thousand words, and can save a ton of hours.
Thanks again, Greg.
Thanks Cnut!! I attempted to install the used booster I purchased for mockup which included the master. I was disappointed it fouled with the coils on the LS2. But after looking at the nice nomad video again I realized the booster can be mounted 180 degrees from how it was in the van it came from. So looks like it will work. Now if I can get the rod out as you discribed I should be in business. Looking back now guess I should have just looked at the first pics you posted in this thread that show the correct orientation for a trifive.

Success!!! After attempting to remove the rod from the booster with a big hammer I gave up did some research and found folks had made a make shift press devise as Cnut discribed but reading more info there are 2 types of boosters one has a removalable rod the other has to be sawed off and pulled thru the booster during rebuild. Anyhow a guy on the chevelle forumn just cut the flat off the existing rod and threaded it. So I did. It works perfect on a trifive bolted right in.
Thanks again for the bracket Laz!!!

Cool! I actually tried to do the same on mine but decided to just pull it out.

I thought about pulling the ball out of the crimped socket, and tried meagerly to do that. When it didn't easily come out, I decided instead to thread the shaft using a common external thread die, after cutting the eye off. Worked out fine. So there are several ways to skin the cat.
It's been a few years, I was able to score a brand new never used Astro van hydroboost off Ebay for $60. Used to be quite a few on Ebay, but I haven't looked recently.
