on my 65 thr steering pump is leaking badly and I was figuring id just replace. what other cars share this same pump?

 

I'd be willing to bet any gm pump of that vintage would be about the same... Not sure when they went to the newer style, or if its a direct bolt in to the one you have. If nothing else this should be good for a BUMP. Good luck

 

My question would be, where is it leaking from?

You may just need to get a seal kit for a few bucks from the auto parts store.

Or consider having it (and perhaps the steery box as well) rebuilt!
It will be more expensive this way, but they will be guaranteed to fit, function, and look perfectly for many years to come. You could even upgrade to a 12:1 constant ratio in the box if you wanted.
If they are 40 year old originals, it could just be time to do the system.

 

I have this one laying around. Not sure exactly what it came from over the years, but it's definitely period correct.

 

The basic Saginaw PS pump was used from the early 1960s through at least the 1990s. The pump body is the same on all, but the sheet metal reservoir varied by application. Usually you get a rebuilt pump and swap the reservoir - it's a bolt-on though the O-ring can be stuck.
