I need help. I have a project car that has the mustang 11 front end with 9'' 4 lug disk brakes that I want to change to 5 lug. I think it must be 1974-1978. Can I just get after market 5 lug rotors for the change? If so what year do I need for the switch? Also have the 8'' rear end. It measures 58'' drum face to face. What is recomended for this swap. This housing has the taper on the outer ends so i was told I cant just change the axles. Do not know squat on mustangs but I guess I will when this car is finished.
