Well, now I'm not so sure. We pushed the fan off of the old pump and found that the shaft on the new pump is much too big to accept the fan.
So here's my problem: I have all 3/8" pulleys and a stock fan and it wont fit, and according to sources much more knowledgeable than me, there was only 1 type of fan made for the 47-53 models.
Check out this pic...it's the water pump that's on my '53
