Here is a list that will fit. you just need to choose your size you want.

Gates number and size

36101 70mm
38006 76mm
38005 82mm
36157 87mm
38001 90mm
38012 90mm Plastic
38002 100mm
36119 102mm

These fit on both idlers and you can use any of them to make your belt tension correct.

change the idler pulley instead of the belt. You will get better belt wrap.

Stock 3.3 pulley, the math says 9.88psi, so probable 8-9 with pumping losses.
