I just ordered an underdrive pulley kit fom GREDDY. It is my understanding that the kit comes with a belt that eliminates the air pump. That would be a good thing because I want to take mine off at the time of replacement (no Cat... I live in Florida and love the rules here!). If that isn't the case, I was curious if anyone knew what size the belt I needed to get to take the air pump off. Also, curious if anyone knew off hand the size of the other belt (The belt closer to the front of the vehicle). I was going to replace both belts at the same time and the manual doesn't specify a size. I wanted to have the other belt in hand by the time the pulley kit showed up. If not, I'll take the old belt to a parts store for replacement. Thanks.

Im almost positive that the Greddy kit comes with the belt to remove the air pump. If not then sr motorsports sells the belt for it. They also have the other belt you said you wanted.
