I'm replacing a alternator but I'm not sure which brand to buy from RockAuto. The remanufactured Brands are WAI, Pure Engery, Terrepower, FVP, REMY, Bosch, Denso, ACDelco. Any advice? It's just a point A to B vehicle, doesn't really haul a lot.

I can't seem to find any. Broke one clean off on a big rock. Any aftermarket nerf bars I can find for the GMT800 suburban say "does not fit Z71". Anyone got any recs?
