Can an automatic frame be used in place of a manual transmission frame? What is different about them if they can't be swapped? Are the frames the same from 74-79?
Can an automatic frame be used in place of a manual transmission frame?...
Auto in place of manual....Yes, provided you swap out the clutch bracketry if you want a manual transmission.
...What is different about them if they can't be swapped?...
The clutch goodies. 68-79 manual transmission frames have the clutch bracketry welded to the frames. 80-82 manual frames have the bracketry bolted in place. Automatic frames do not have the cluth hardware.
There is only 1 bracket that needs to be welded on the auto crossmember so it's not a big deal to use an auto frame. IMO, the convenience of the removeable crossmember is a big plus with an auto frame, if you're not concerned about originality.

You probably allready no this but just forgot.No 82 manuals.
