if you get the part number I would love to have it! As for now I just carry the water pump pulley with me and old belt in case of an emergency. I have really no time on the car since I installed the little motor. Again waiting for my son to come to town before I go blow up the car! Lol what was the shortest time the motor lasted? Like do you think I'll make the 5 miles to the track about 10- 15 passes and the five miles back before the motor goes out?
