a few of the existing holes in the frame for the rear brackets line up, but the front brackets are based off of a hole you have to measure 3-4' away from. I guess as long as the wheels are centered not much else matters.

Bob you did re enforce something for me on the "overboring holes at the X" That part made little sense to me in the instructions, but I think it clicked for me now. I guess I'll have to sort through the hardware and figure out on my own by elimination what is used where and where the strange washer like spacers go exactly.

I might call CE and see if they have a write up like other companies publish for various kits.

One other question...the kit specifies a 67-69 camaro or 68-74 nova rear...I have been looking for one for a while, but I'm not really in a good area to find one. I had been thinking of using an s10 rear and the thread about s10 rears got me thinking again. What would be the reason the kit specifies a camaro/nova rear and would an s10 rear work (fitment wise) just as well?
