Thread: supercharger pulley

well i swapped my stock pulley wit a thrasher press on pulley 3.4.......Thrasher Press-On Supercharger Pulleys: 3800 Performance

and when i go to put the screw back in thats on the side it is to small now???? should i just buy a bigger screw with a washer?...if u look at the pick u can see a little 1/4" nub that comes out on the side that makes it to long for the stock screw. can u follow what im sayin or not?
