Since the A-car line of General Motors was to be aimed at a different audience for car buyers not desiring a full size car or a compact, this is where the senior compact (a Buick term) or midsize came into play.
*1964-67 A-bodies used the same frame design, but different models and bodystyles utilized various body mounting, while all frames had a 115 inch wheelbase, which is similar to the 1955-57 Chevrolet.
*1968-72 frames had two different wheelbases, a 116 and 112 inch wheelbase. Sedans , station wagons, and utilities like the El Camino used a 116 inch frame, and the frame is interchangeable, except that the sedan had non-boxed rails.

Thanks John for your quick reply. Now I'm wondering if, a 69 Velle would go on a 65 frame if you moved the body mount pads that are welded to the frame.

In addition to the length difference, the widths and features are different also. Pulled these images off a goggle image search

Those have gotten around quite a bit... I scanned them out of some of Dad's old frame books about 10 years ago.
Did the frames change with the different generation Chevelle's? Or, are the frames 64-67 then 69-99 then 70-72?
Reason for the question. Will a 69 Chevelle go on a 65 'A' body frame?
