Cody - your parts were actually being picked in the parts warehouse when I inquired about them. The trunnion was in stock and the tires came in yesterday.They are going out today.
As far as the small screws that keep the pulley tightened to the shaft, check to make sure that there are two screws in the small hole. The top one needs to removed completely before tightening the inner one.
We apologize for the inconvenience.
