Thanks, Art.

Art, the 7.5 GM has 26 splines vs 28 for Ford 7.5 and 7.65 GM.

Considering a 7.5 GM carrier into 7.5" Ford case. Likely machining required. JH bound.
Thanks,, Art.

Won't be as durable as the stock R&P.

Carl, I haven't got into the Ford yet. I like 28 spline axles, maybe no C-clips ? Have a Gleason for Ford. Either is stronger than the JH, which has no posi available.
Cheers, Art.
