Newbie on the forum but a long time Mustang owner over the years. Looking to do a resto mod on my 72 Fastback. I have a chance to purchase a 9 inch that came off a 64-69 Mustang. Would this work on my 72, and would it need any modifications to fit?
Welcome to the forums! Looks like you have a nice project. The third-member will fit if you have a 9" housing in your '72. You would need to check the axle spline count (28 vs 31) to determine if you axles are compatible.
