Dana 60 S60 or Ford 9"

Whether I go with a 9" or a S60 Dana, It will be narrowed/ 4-link brackets etc. 40 spline axles, pro ring gear etc.

Like I said before, I am not going to be changing gears often, if at all. The only time I would prolly ever change a gear is if I was installing a fresh one, or just experimenting.
