what do you mean by "rebuild kit"?
like pinion & carrier bearings, wheel bearings, or both?
as far as I know all bearings are interchangeable between ford/gm/dodge open knuckle 60s, but don't quote me on that one.
the only 35 spline outters currently made are for GM & Dodge only. Ford uses a shorter stub axle, & therefore they won't swap in. I have heard of people adapting them though, & rumor has it a company is working on 35-spline Ford chromoly stubs, but I havn't seen them yet.
