I guess the brand name should be on them somewhere. If you get a hold of a stock set you can compare the outside diameter of the pulleys to eachother.

Might beable to tell by the color of the pulleys? I bought BBK steel pulleys and they came powerder coated black to match the stock pieces.

You are running a clutch type fan? What kind of issues are you having? How about the alternator, is that still a stock unit or upgraded?

if they are underdrives, the crank will be small and the water pump will be large
