When I bought my 87 iroc the owner had removed the air conditioning out of it... my belts is now squalling pretty bad. When I replace it what size belt should I use? Would the factory replacement be to big? Should I just get the one made for no ac? If someone could give me some info please

 

Not knowing exactly what your particular setup is - the size should be printed on the side of the belt. If not, pull it off and measure it. Or take it to the parts shop and compare to new belts.
