All you have to do is swap out your original rotors for the Mustang II 5 lug rotors. They were on most V8 models. DO NOT use wrecking yard rotors under any circumstances. Buy them new.

Sorry but I can't help you with the rear ends, but someone will be able to.

I thought that the early pinto (71-73)was different from the 74 and up pinto/mustang II.
I went to do a swap one on a guys 40 ford with a 71 pinto donor car front end and had to swap spindles because the bigger rotors with 5 lugs would not interchange. ( I am reasonably sure of that)

I know for a fact that the calipers and spindles and ball joints are different. You can put the later spindles on the early cars and they are slightly taller. So you get an added benefit of having a lower roll center.

Later, mikey

They are similiar, but not identical The PINTO front suspension was updated in 1974 with the introduction of the MUST II (both used the same suspension). There was no 5 stud MUST II rotor. The 5 stud was reintroduced in 1987 (limited) on the FOX MUST.

I think the 10" early RANGER 2WD rotor can be adapted to the MUST II spindle but the DIA must be turned down slightly (I will have to research this). You would most likely also have to go to the 74/ spindle to make the update easier (need to research this also)

You can also have the 71/73 rotor (9 15/16" DIA.) stud pattern redrilled to five stud and have the other holes filled to save you some parts swapping.

You can also (with 74/ spindles) use a 11" GRANADA rotor with a disc brake caliper mouting kit from ROD AND CUSTOM MOTORSPORTS (please use FORD caliper kit).

If the rear is an 8.8", you need two driver side axles (and drums) from a 91 RANGER (the years are more than 91).

I could have sworn that the '76 Mustang II Mach I (302 V8 w/4 speed) that I purchased brand new had factory 5 lug rotors. Might be wrong though since that was 30 years ago and I do occasionally suffer from CRS.
