ANyone know what axal the 1973 mustangs with the 9in rear used? I think theres like a 27 and a 32? Not sure which I need. IM thinking it might be cheaper to get a allready rebuilt rear with 3.70posi and install it myself then to get mine rebuild as it is now with stock 2.75 and open rear.

Thanks,
Jim
