Anyone using sterling rear diff from a super duty. Are there issues I need to know about. The van I am converting has rear drums and I want to go disk so if I use the sterling it will match 8 on 170 pattern for super duty front.
Chris at U-Joint off-road has a hardware package to stuff the Sterling axle underneath. It's a common upgrade. QuadVan installs them too (they don't offer any kits however).
