WTB, older style cabin door trucks/wheels

[GrandMaster]

Anybody have some of the older (mid-'90's vintage) sliding cabin door trucks/wheel assemblies for the top and bottom tracks that they want to get rid of?

I know where I can get the newer replacement style, but you have to replace the tracks with those and I'm not really interested in removing the door & all that goes with that since theres really nothing wrong with my current tracks.
