I have 85 & 86 GTs. One is having smog pump noise issues. Since Im getting classic tags I don't have to pass emissions for inspection. To remove it can I just get a shorter serpentine belt and omit it from the loop or do I have to buy a delete-pulley kit? I'm at work now and not looking at the angles of the loop, but the thought just occurred to me and I'm sure someone ran across this before.
