So I have a 65 mustang, and I’m narrowing an 8.8 out of a 99 Ranger. So assuming the narrow goes well, I have to weld perches. So just to confirm:

Pinion angle should be set at ride height, or with a jack under the rear ended compressing the spring?

And I should just match the angle of the stock 8”? It’s probably worth noting that the driveshaft will have to be shortened, which I imagine will affect pinion angle.

any suggestions guys?



Thanks
