    Currently I have 3.23 gears behind 4.8 with a a small 207/217??NSR cam. The nv3500 has been rebuilt with heavy duty parts and I’m ready to put a posi unit in and re-gear. Searching the forum it seems like a lot of guys with autos go with 4.10s seems like it would make 1st pretty useless spinning my 28.6” 275/40R20s. Anyone hear re-geared a manual truck?
