NAPA auto Part prt#38-5136 swap out the pumps and pressure valve from your original pump. Probably cost you $50. Or go to any local parts stor3 and get a power steering pump from a 1990 Chevy 2500

Does look like the saginaw pump and as 47ex mentioned, if it is just need the pump. Keep the valve off old pump, can replace the whole pump with tank, or just the pump

Pic for reference only

Yes its just a Saginaw pump. swap it out of the existing reservoir. Done this many times especially on the earlier 1075's earlier set up. the last few years of the 1075 they changed the bracket s and better adjuster so you wouldn't put to much force on that pump to adjust the tension of the belt. To much tension breaks the back of the power steering pump shaft. To little and the belt squeaks when running in rough water.

Yes this is the correct pump thank you. We damaged the pump wholes a little in the back of the housing (only one pump) while removing and when reinstalled it had a little leak in the back around one of the wholes the lines hook up to in the back but we cant tell which one is leaking because its behind a bracket and if we find the leak how do you fix the damaged reservoir can?

there are plastic washers that go between the pump and the reservoir case where the bolts go in. You probably have one that is no good or slipped out of place.
