Power Steering pump woes

[69GMCLonghorn]

So on a 70 C-10, my P/S pump has crapped out. Every single place I go or check online doesn't have the right pump. The fitting in the back points in the wrong direction. Or the reservoir is the larger one with more of an integrated look, rather than the original one that has a top on it more like a wide snorkel. I think it's called a Saginaw type. I installed the new one and now it's offset from the crankshaft pulley by about 3/4 of a belt width.

Does ANYBODY know where I can pick up a new (rebuild from Thailand??) original style pump for this thing?! I've fought too long with it and I'm almost out of booze. Help!
