B Body 8.75 in a an body

I put a 66 B-body 8 3/4 into my 1974 Duster. Moved in the spring perches. Other than that I didn't have to do anything else. I went from an 8 1/4 3-Speed to a 8 3/4, 4-Speed and I did not have to shorten the drive shaft. But, I did have to change the yoke.

Rims and tires you will have to measure, measure and measure!

I hope that helps.
