5.2 Magnum into a '72 Scamp-tips?

Ok, so the engine is now in the car. I ran into a couple issues-both of which I'll tackle as the time comes available.

1) Fuel pump no worky. Not sure on this one as I can't see whether or not the fuel pump eccentric is actually spinning, but it would appear as such since I know the pump did work when I pulled it from the old engine, and I'm running a Hughes cam snout extension for my new engine. I can touch the new eccentric, but I can't tell if it's secure nor do I know if it's actually moving the pump arm. So, the front end of the engine may have to come back off....Grrrr

2) I went to put on the alternator only to discover the old swing arm bracket doesn't bolt on the head because the mounting pad where it should go is about an 1" too far forward. Ok, no biggie I figure...I can modify the bracket to fit the new engine. Then comes the really fun part-the alternator-I installed the pivot bolt on my a/c compressor brackets only to find out the the alternator won't even swing down far enough to allow me to use it even if I had modified the bracket because it actually contacts the cylinder head. This wasn't something I'd read about in regard to Mangum swaps. I guess more people do non-a/c vehicles, or keep the accessories as installed on the donor engine.

If you guys have any suggestions, I'd like to hear them.
