Jim, The photo came through as a thumbnail, so hard to magnify and get resolution, but it sure looks like they installed an elongated bolt on the upper arm to compensate for the mismatch and knowingly kluge it rather than address the problem.

I do not know if what is there is 'correct' or not. When I had PIM do the restoration I ordered their alternator upgrade. I just took it on faith they new how to do that work since they had the engine rebuilt/upgraded. I guess I was wrong. This is not the first discovery I have made of what appears to be improper work. The car is in its capsule for the winter so it will be May or later before this can be addressed. The mechanic that discovered the situation did not indicate a misalignment between water pump and crank - just the alternator to water pump issue. He asked me if there were after market offset brackets for the newer style alternators and if not suggested what Mike Drew suggested - that is machining off some of the boss of the alternator. I have attached another picture that I think more clearly shows the pulleys and it appears it is the Alternator out of whack. So, I think the approach will be to try to adapt the alternator by probably grinding down the boss some.

I ask because in the photo it’s hard to tell but the alternator adjusting bracket looks to be in-line properly. It might not be. Compare all pulleys and see which ones appear to be out of line. If the alternator and crank pulley line up, then the one on the water pump is wrong. In fact it could be a wrong water pump with a shorter nose. Examine it a little more and let us know what you find. Asa Jay Sent via radio waves

All,
This past year for the first time since restoration, the bulkhead cover was off exposing the front of the engine.
A mis-alignment of the alternator to the drive pulley on the water pump was noted.
Is there another offset bracket that should have been used with the upgraded alternator or is there another solution anyone has for getting things back aligned?
Thanks,
