here's an interesting piece of information that I found on this site
http://www.brphotrods.com/products/2...cts/index.html apparently there were two different crossmember mounting locations on the second gen Camaro subframes depending if it was the 1970-74 Early Style or the 1975-81 Late Style. I recon hardly anybody would butcher the Early ones, so most likely mine and most of youz is the Late Style.
now I realize that I will have to make something custom but this is just some fun facts, I think the Camaros came with a SBC 350/TH350 combos or Big Block / TH400 but I doubt they had a SBC 350/TH400 Option like mine in the 75-81 Late Style.
