Also looking for that information for a friend. Considering a 67 body going on a 66 frame.

I currently have my 65 on a 87 blazer frame and i dont like how it turned out with the rise in the frame on the blazer at the back the bed had to be way high and so did the cab it had to sit off the frame like 6" the cab did and the bed is way higher could of made the bed inside shorter but dont like that look so maybe a shortbed or longbed frame of that era may not be so bad but would have to cut to the right length of 115" wheel base and now i have bought a 63 GMC frame that when got it home found rusted apart behind the rear shackles and my 66 2wd frame is rusted and pitted where the coil spring mounts are so now I am back to square one
