So, after waiting a few weeks I finally got my shipment from S&W race cars.
Steel tube formed rear frame rails, new front subframe tie in bars, new rear down bars so I can run a back seat, and some extra tube for a diagonal on the main hoop and whatever else I may need.
Also, finally picked up the vette

Ignore the trailer strapped to the roof, my landlord wanted me to grab it lol
And started tearing it down today. Looks pretty simple with all the plastic and fiberglass parts torn off:
Did a bunch of measuring today too. Think I figured out a game plan. Believe it or not the frame rails before and after the control arms on a c5 and a first gen are actually within a half inch of eachother.
Tomorrow I'll most likely get the front clip cut off and finish stripping the vette chassis. Once I get them side by side I'll be able to finalize some things.
This should be a huge improvement over the 40 year old technology that was there:
