Lateral-g Forums - Suspension Dimensions

Im lookin to design a subframe for my 68 Camaro. I have Solidworks and Pro Engineer and I was going to model it up in either one of the prgrams and I was wondering if anyone had dimensions for the 4 subframe mounting locations and the center distances for the lower control arms. Or if anyone knew where i could see a copy of the old drawings from chevrolet or what. I was planing to use the DSE Coilover conversion for my upper mounts and then design the rest of the frame. So if you guys have any pointers or inputs feel free to chime in. I want to try and use stock components so i can use dse control arms and sway bar and stuff. Thanks in advance!
