Reply to "New Altas 100T Trucks too small of centering hole"

Joe, I often think the same thing. Sometimes, I end up moving the gearbox back just slightly and drill and tap new holes. If you do that, you need to trim/grind off the lip on the top cover plate. I noticed the gearbox provided with the lionel 86' boxcar also uses the 746 long shank coupler.

I've used the 746 on some passenger cars to support the diaphragms and they work out nicely. Only issue sometimes is needing to trim the lower portion of the diaphragm to allow the coupler to clear.
