68 Mustang Engine Swap pulley problems

[houseboatduhg]

I have recently run into this same situation. Twenty years ago I dumped a 302 from a 71 torino into my 68 fastback. Everything worked great for the last twenty years, but I recently ruptured a hole in the bottom of the radiator, so I purchased a new alluminum radiator, that's when I reallized I must have used the torino radiator. The outlet for the new radiator dumped to the passenger side and water pump pick-up was to driver's side. So I bought the mustang water pump, but power steering and alt. brackets were different. finally got that pretty much sorted out, and then last night went to mount the water pump pulley and it hit the lower pulley and is 1/2" to far back. Any suggestions?????
