Ford 8 inch rearend swap

Then that means that the Ford that it came out from under has the same basic spring perch and wheel house measurements as the car you're putting it under. If the cars are about the same size, that's understandable........and that means it's a direct fit. What did it come out of?
That's the idea. I cannot be sure what car it came out of, but the guy listed it as 1964.5 v8... but he got it from a guy, who got it from a guy, etc. It's got 1:3.00 gearing and I think my valiant has 1:2.93(?) or something very close.
