After browsing through the new American Models catalog it appears that their DC scale locomotives and rolling stock come equipped with dummy- -i.e., nonoperational- -couplers. Can Kadee replacement couplers be mounted directly on the loco or car body (instead of the trucks) without the need for extensive modifications to the underside of the body?
The older AM products were designed before the Kadee S Scale 802 was available.
If you're going to use the HO #5 coupler, no modification is needed. If you're using the 802's, you'll have to drill new mounting holes.
Most of the freight cars will just need to have new holes drilled for the 802. Passenger cars will need pads built up for body mounting. Locomotive mounting varies from unit to unit.
