The tranny is most likely an SM465. I don't know of any other 4 speeds used in '72. The rears came with multiple gear ratios. You will have to check it yourself. The best way to do this is to pull the rear cover and look.

Welcome to the board. I would get acquainted with the search function on the site. Their is lots of info and pretty much anything that you can think of has already been covered many times.
