Yep ... 'cause the distance from the block to the pulley flange is
less for a 3-main water pump than a 5-main water pump. The 5-main
pump has a greater capacity than the 3-main pump. You can fit
the 5-main pump and pulley, but you will need to shim the radiator
forward to compensate for the difference in the pumps ... more than
likely this was done to fit the 5-main that you are replacing.
