    1979 Trans Am vs 1981 Turbo Trans Am Subframe and Suspension

    I can think of that would be different would be the spring rates as the 301 is lighter than the 403 and the frame mounts for the engine. Possibly the sway bar rating. The diameter of the 301 might be smaller. Otherwise, it should be straightforward.

    1971 T/A Door Interchange

    Good afternoon all. Can someone tell me the difference between the 1970 to 74 doors and the 75 up doors? Thanks.
