I replaced the compressor with a bypass pulley recently. the bolts that were provided wire too small for the holsews so I used old bolts with washers to make up the undersized frame of bypass pulley. first question is should these bolts be undersized and why? did I get the wrong part? the size of the pulley itself is the same diameter. it barely fit the holes but was able to get it on after struggling with washers. when I went to put belt on the belt would not go over tensioner. I then had to pry the belt on like a tire on a rim onto my crankshaft pulley. now when I start it it is constantly squeeling. I did not try the washer I believe something else is wrong. can someone please enlighten me? thanks Ryan
