there was some info in this thread... with me no really knowing the sierra's that well doesn't help that much...

So it may not fit?
the pump itself will fit, its the pully on the shaft that you may have issues with.. but if your upgrading the alternator to a 110amp and changing pullys then this is not of any concern as you can use the swift pully.. but you will need to change the crank pully, at the same time..
