Getting some ready for GM....need a little help with some items:

water pump pulley BB 3874416 BR

crank pulley BB 3876844 BU

power steering pump bracket 3987422

frame mount for engine 3980942

??? what is the difference between the 30140 12 bolt posi carrier and a 30174 unit....they both look the same to me.

I have a set of 4.10 gears...ring gear 3862526 pinion 3862514 are these std items or something special...??

thanks, wilma
