Crank pulley and/or water pump pulley

It's a '78 engine with a cast crank from I don't know where that is now internally balanced and has a new balancer on it for that. That pulley looks the same as what I already have. If you measure the snout I bet it's rocking at about 1/4" shorter than the 1 3/8" I'm looking for. I'm trying to get the wp pulley grooves back 1/4" or the crank pulley grooves forward about 1/4" from where they are to make everything line up. I'll try to get some pictures up on here later of what I have.

The difference front to back from the wp pulley mounting surface to the crank pulley mounting surface that I have is 4".
