i need the design but i want to know if the waterpump pulley from the 95 5.0 and use it on my 90 5.0 will use the same 4 bolt holes.i know the shaft diameter is larger on the 95 but i don't think it matters.the problem i'm having is belt squeal because the belt rides up against one of the edges on mine.if it has only edge or rim on it i think it'll work.any input would help.most everthing is aftermarket such as vortech,bigger alt,no smog ps delete etc.its a real b_____h getting pulleys lined up.i think i got it with the exception of the water pump.
