Here's a few photos of Mopar Power steering pumps. I'll make this thread a sticky. There are always questions.

Here's a quote from Slantsixdan about this pump pictured. The pump in the pic appears to be a Thompson/TRW item. Federal and Thompson pumps are interchangeable on the same brackets (though you have to check pulley alignment; there are multiple different pulleys for each pump); Saginaw pumps take different brackets. The early Saginaw pump has an oval filler neck and a scalloped plastic combination cap and dipstick. The late Saginaw pump has a "ham can" shaped reservoir rather than a round section housing the actual pump at the bottom of a filler neck, and still uses the scalloped plastic combination cap and dipstick.

I'm trying to find the correct pump and reservoir for a conversion I am doing. The big question is do I need the new or the old style Saginaw pump/reservoir. I am going to use Classic Industries part# MD2675 bracket for an LA small block to a Saginaw pump but I'm not sure which pump will fit. I am also ordering the hoses for Saginaw to Mopar (MN7508) and a conversion steering box for 1962 to 1976 (MN7505). Can anyone point me in a direction? This is for a 1964 Dodge Dart SW with a newer LA 360 and a newer K member (though the K member shouldn't be a problem since the box is 1962 to 1976).
 
Id like to run a Saginaw Type 2 pump but it seems like no one makes the brackets for Mopar. I hate the old Saginaw pumps I have had nothing but problems with leaking/weeping pumps over the years.

Chrysler used the later pump up into the 80s on LA motors. I don't know about your part of the world but in the States you can score everything you need off trucks + vans at the junkyard. Mine came off an '85 Fifth Avenue.

And GM used the same pump at least into the late 70s.
