I am putting a '61 292 Y Block in my '54 Mercury which I thought was supposed to be a direct swap. Everything was going fine until I tried to install the radiator. I discovered that there is only about 1 1/4" clearance between the end of the water pump shaft and the radiator core. I am using and 1 1/4" fan spacer but with this small amount of clearance I can't see how there would be enough room for even the thinnest spacer and the fan. Anyone else had this problem? What am I doing wrong? I am not sure how to attach pics through the website but I can send pics by email to anyone who thinks they can help me. Thanks, Alan S. Freeman
