The remains of the day

A while ago this came back into my possession after a stretch of time.

This model was the original plastic master for my resin cast Df/Dft models. Obviously it has seen better days.
A cursory look reveals that most of the bits are there, or I can fabricate replacements. One thing that I can't remake is a Bachmann SD40-2 bogie from the second incarnation of the model. The first incarnation (from the id 1980's) was a good mech. However its weak spot was the worm gear, which after a lot of running, would wear out the plastic end bearings.

So, does anyone out there have a Bachmann SD40-2 bogie that I can buy off them?
