Where do I find frame dimensions for my '64 Special, are they the same as a Chevelle and other 64 - 65, 2 door GM A bodys?
A body shop with a frame straightener should have the dimensions if you can't find it online. Some of the chassis service manuals have it in them.
http://v8buick.com/showthread.php?t=223310 Frame dimensions should be toward the bottom, photobucket link. Should be the same, 64-72 I think. Correct me if I'm wrong. I'll see if I can't find a 64 frame diagram manual tommorow to compare.
I have a pic of the 66 frame dimensions over at 65gs.com: http://www.65gs.com/GS_Gallery2/displayimage.php?album=22&pos=23 'click on the 'next' arrow for page 2. 68-up have a longer wheelbase and rear upper control arms are a different length. Chevelle frames are a few inches shorter than the BOP cousins..... definitely, 66-67, not sure about the other years.
