Just get the one that fits your water pump (long or short).

As a side note, there is a dual groove water pump pulley that has 2 different diameters. It must be used with a crank pulley that also has 2 different diameters. The larger pulley groove is for the alternator to overdrive it to maintain output at lower RPM.
PatOf course, that's just my opinion, I could be wrong!

The pulleys are pretty close. There's about 5/16" between the pulleys on my motor.Jack

Ditto on the model kits! My best were lost when the Hobby Shop burned under suspicious circumstances....
