Looking for those G Scalers that have body mounts Kadee couplers! Need to find out what coupler(s) were used. Or if I can body mount the current truck mounted couplers. Have 5 USAT cars. The remainder are Aristocraft. Can I use existing truck mounts, or do I need to get different couplers? If so, which one(s)? Or, for a temporary solution, I can create a couple of transition cars. Truck mount on one end, body mount on the other. Might be cheaper!! Information appreciated! Thanks.
