Well yes and no. BBB frames are thicker in the front than the other makes and the SBB. We have a example of this with the frame I just sold to Paul Linhof he didn't believe it until he checked the two frames and the BBB is actually thicker steel around the engine. Now do I know that the other A bodies are not the same , Nope. But they think 1 cowl mount is enough on each side where Buick used 2 Anmyway they can be used throuout the whole line of A bodies not sure if the holes are all there for the mounts though
