I need to put acoupler on the rear of my IHC Mogul tender. The old one got damaged and was fastened to the bottom of a plate which in turn was fastened to the truck bolster. The plate to the bolster is all that remains. I tried a Kadee #148 whisker draft gear box but the rear hits the truck rear axle and protrudes about 1/8" too far. So I tries a #37 that has a very short draft gear box. It will fit if I could get all four pieces to stay in place so I could glue it to the plate. I do not think anyone but a finger contortionist could assemble any of the “30” series coupler springs. I thought the #5s were bad but not any more.
Any ideas on what to try next?
