I have a 66 Chevelle with a badly bent frame, I also have a 65 Buick Special,does anyone know, Will the Buick frame fit the Chevelle? Thanks, Dan

I answered your other post and I had this issue a month or so ago. The BOP frames are longer. It make them work you have to shorten the frame between the rear frame mount bushings by 2+ inches. In some cases the body mount bushings are also located differently. '66 Chevelle rear (middle) mount is welded to side of frame. Others are located center of frame rail.

You can make it work, depends on what pasrt of your Chevelle frame is bent and which one you want to tinker with. there is no direct repalcement other than another '66 Chevelle frame. Even the '67 has a few differences but minor.

Good Luck
