Hi Guy's New to the site and eager to learn from so many knowledgable Tri 5 enthusiasts

I have been d a looking for some time at all the aftermarket Chassis's on the market. I have decided that I would like to keep at much of my 55 in my car as possible. That being said I want it to drive as good as I can get it using the original Chassis but upgrading the suspension front and rear to " C4 CORVETTE " . QUESTIONS, TIPS, ADVICE , IS THERE ANYONE THAT SPECIALISES IN THESE CONVERSIONS. PREFERABLY, CALIFORNIA OR ARIZONA, ALSO ANY REVIEW'S FROM ANYONE WHO HAS PERSONALLY DONE THE SAME CONVERSIONS .
ALL HELP APPRECIATED AND OPINIONS RESPECTED

I have a Classic Edge Designs C4 conversion chassis under my 57 Nomad. Laszlo Nobi (Ft Collins CO) was doing these conversions using a jig he put together. All told, I think he did 40+ of them over time. Mine is probably 10 years ago now, and he's since then shuttered his business doing these chassis conversions. He's on this forum as ChevyNut, and he may chime in here about where you can find someone to do the conversion. He sold his jig and tooling when he closed the business.

I was looking for a more financially reasonable way to achieve a modern suspension under my Nomad, and wasn't interested in the stock suspension aftermarket spindles, AArms, 4 link, etc. Also couldn't afford a Morrison frame at that time. So his solution fit the bill.
I bought the front and rear C4 components locally, and simply bolted them in when I got the frame home.

Laszlo built a wholly new front clip using the C4 cradle allowing the C4 steering rack and C4 AArms to be identical to the GM spec of the Corvette.
He fabricated mounting points for the C4 IRS rear end to bolt right in. I used ViKing double adjustable coilovers at all corners and they can be adjusted for both compression and rebound to get the ride either smooth (for cruising) or stiff (for canyon carving).
I had Laszlo add some Morrison bought "cross pieces" in the center of the frame to further stabilize it from twisting (because the stock frame is fairly thin gauge metal and will flex when you drive on uneven surfaces).

Short answer here is I've been driving it for several years now, and it drives like a slot car.

Here's the frame when I got it home to SoCal (from a quick 2 day'er to Ft Collins to pick it up= hanging out the back of my shortbed F250.
