John Deere 14sm, 14sb, or 14se Green Deck Parts

I am looking for some parts for a late 80s John Deere 14SE (this is the version that came out before the silver deck models). I am mainly looking for the rear height adjusters which are JD part number PT12457 and PT12458. But if you have other parts for this type of mower please let me know what you have. For reference this mower would be comparable to the one in the photo....as long as my attachment works.
