I went to a junkyard yesterday in search for an a body rear, either 8 3/4 or 8 1/4. Some rears were laying around and I could use some help figuring out what they are. Pictures of 2 different rears I thought were Mopar
The 8 inch ford is worth a closer look. Early mustang and falcon v-8 cars that used them had a 5 on 4-1/2 bolt pattern and have 43 inches between the spring pad centers. An upgraded one will handle 450hp reliably.
