The pulley I have doesn't seem to fit on my new water pump for some reason. The old water pump shaft measured .75 while the new shaft (same part number) is .748. This is a NOS pump, not after market. I actually have 2 new pumps and both measure the same. Not sure why the shaft would be smaller, but the press fit pulley doesn't stay on. I hope to try another pulley for better results.
I have both pulleys on my 84 duke but getting them off could be trouble due to our current cold snap. Are you in a hurry for them? PM me if interested...
