Overheating issues

If at all possible, I would like to find a water pump pulley that measures 5 7/8"X 2 7/8" That would be ideal in my situation.

ok, measured the water pump pulley i have. 2 5/8 deep x 5 3/4 dia. re-check the depth on yours, but it looks like what you want. you can use a spacer to get this one lined up if needed
