Jay,
our problem is solved...I think..I have the “Sunset Models Care and Feeding Instructions for GE 70 Tonner”
Sunset says that the “universal parts” are all Athearn...I found all the parts on EBay...
* 1/8” x 3/32 worm gear universal couplings (6) #40051 @ $3.66
* universal drive shaft...I purchased the last one...🤭
So I think this solves our parts problem...🤔🤔🤔
I’ll let you know once I install the new universal coupling...right now the super glue seems to be holding...
