Bachmann HO GE U36B engine

[smithron455]

I have the chassis for the 1970 version of the Bachmann GE U36B engine.  It's assembly chart is Item Number 41-0640.  I have purchased a shell for the chassis.  I need the front truck outer frame which is part number 3201-2.  I also need the 2021 horn-hook coupler and 1997 traction rings for the rear drive wheels.  I suppose that I will find out that these parts are no longer available.  My hope is that the same front truck outer frame was used on other models and is still available under some other part number?

Any help?  Any ideas?
