Ford 9” dimensions

[Hipopinto]

Hey all

When they built axles for the leaf spring equipped cars did they “center” the yoke in the middle of the car?

I guess what I’m asking is the yoke supposed to be close if not centered between the leaf spring perches?

I have a small bearing 9” in my pinto that I believe is from a 64-66 mustang it fits very well but I’m thinking of building a new one with large bearing ends and I want to run Calvert racing springs and Calvert CalTracs

I’m trying to avoid ripping the rear out of the car until I can just bolt this new one in place!

By chance is there anywhere I can find dimensions for mustang rear ends? Like housing widths, perch centers, and yoke placement?

I can get pretty close with the rear installed in car but I would like to be exact!

Also what is the difference from axle mounting surface (where wheels bolt on) to the housing end?


Thanks
Dave

All mustang rear housings are centered. Spring purches 65-70 are 43 inches center to center. I thought 71-73 purches were further apart but according to the chassis dimentions they are 43 as well.
