Pulley and belt alignment problems?
I'm wrapping up the rebuild on my 82 slant D-150. It's the same block, same power steering pump, same bolts, same everything. But the pulley on the PS pump doesn't line up well with the crank pulley. I know the crank pulley was fully seated when installed. I just double checked it, verifying it lines up perfectly with the alternator and fan pulleys.
Using a straightedge to check the pulleys, and pulling the PS pump as far forwards as I can, there is still about 1/8"-3/16" or so of misalignment between the pulleys. Here are pics measured at the top and bottom of the PS pulley.

A visual check of the pulley has some indication that it may have been this way originally. I don't know for sure as I didn't notice anything odd when pulling the motor for the rebuild. The radiator side of the PS pulley groove is polished down a little over halfway to the bottom of the center groove. The rear side of the pulley is only polished for about a quarter of the distance to the bottom of the groove.
Is this a big deal or not? If it isn't likely to cause a problem I'm inclined to run it as is. If it needs to be fixed the only way I see to do so would be to remove material from the rear of the mounting holes, effectively letting the whole unit move closer to the radiator.
