I forgot to ask something. Dave, you mentioned using the adaptor plate along with the original water pump. But I replaced the original with the short shaft pump because the original wouldn't allow the fan to clear the radiator. I was under the impression that the adaptor plate raises the fan to the center of the radiator, but it seems this would also reduce the distance between the block and the radiator by 1/8th to 1/4". If that is the case, how can you use the original pump which lacked the clearance needed? What am I missing?
