Well I took the old cylinder to a repair shop yesterday and the guy was very honest, saying he hates to turn away business but my cylinder would take a lot more work than it's worth. He also mentioned that on these older loaders the rod itself would often bend and need to be straightened. My rod was not bent, but scratched in several places.
I told him I had found this one for $180 and he said he couldn't compete with a rebuild at that price.

I ordered this one rather than the Northern Tool one because it was cheaper and had free shipping, besides having a bit higher PSI rating.
He did caution that the specs needed to be exact or I'd have problems with uneven lifting and probably destroy the new cylinder.
