I figured this would be the best place to continue the subject of Electro-Couplers.
The Lionel 2332 GG1 has them. If the contact shoe is missing but the coupler is still in place I would need at the least, a new contact shoe. However, it seems to me that it would be better to replace the entire coupler assembly. Not the entire truck, just the coupler plate and sliding shoe.
In the Greenbergs Repair & Operating Manual for Lionel Trains, on page 169 there is the "End truck complete", part #2332-75. I wish it were only $3.00, as the page indicates.....LOL But shouldn't I be able to get just the bottom plate and coil coupler assembly, including the sliding shoe ?
On the pages beginning with page 651, numerous coupler/truck assemblies are shown, but not anything indicating it would fit a 2332.
