Swap Federal for Saginaw?

[Saetun]

I noticed last night that I've got a small leak coming from my power steering pump. It's been there for a while I'm sure, hidden by the flood of a leak that the steering box had until recently and the 40 years years of dirt & fluid build up in the bay. Now that I've swapped the steering box & cleaned the engine bay, I'm constantly popping my head in there & last night the few drops of fluid caught my eye quick.

So I have a couple of options, Re-seal the Federal pump in there now. Exchange the Federal as a core for a refurb & bolt it in. Or, (what I'd like to do.) use this opportunity to swap in a Saginaw pump & shim it up for a firmer feel.

So, a couple of questions:
Are there any drawbacks to swapping to a Saginaw pump?

Is there anything in the proposed swap I may not be considering?

Is it just a matter of unbolt/bolt in?

Two Saginaw pumps are avail (roundish reservoir & the "ham can") is there any real difference between them?

Thx.

Anyone have any insight on this one?

Could be just your cap leaking, someone should repop these.
Other locations could be solved with a rebuild kit.
Remember these systems were designed with different pump pressures etc.
I had a bad leak in mine and the large resevoir O ring solved the problem, after I filed the big burr where someone clamped it in a vice.
My cap will weep alittle and the fan blows it backrotest:

Has anyone made this swap & possibly the Shim Mod? I'd like to get some real world feedback if possible. If your not familiar with the mod I'm referencing here's the link to where I found out about it.
