maybe you guys can help me out a little... I have a 3 in. blower pulley a 7.25 in. crank pulley along with a 3.2 in. alternator pulley... the belt Im running now is a gates KO81145 which is VERY tight and I think its putting a lot of stress on the power steering pump... if any of you guys have the same pulley set up could you give me a belt size/part number I should be running? thanks
