Hi all, I have a set of MTL passenger cars which all have body mounted couplers. They don't stay coupled well, or couple/decouple reliably compared to other cars I have with truck mounted couplers, so I'd like to try and replace them with truck-mounted couplers, but have noticed the existing trucks have an offset bolster pin (pic below). On the Micro trains site, I only see 6-whel passenger trucks with the bolster pin directly over the middle axle, which won't fit my cars without the truck interfering with the tanks and other underframe items. Do I have any options please? I'd be even ok with going to a 4-wheel truck vs. 6.
