I am hoping someone can provide some information that will help with a coupler issue I am having. I would like to know if there is a coupler avaiable that I can use to swap out the Bachman Spectrum 1:20.3 Body mounted ones, with one that has a longer shank to allow running on tighter radius curves. Most of the curves on my layout in progress are 4 to 5 foot radius and do not present an issue with me running my 1:20.3 , 2-8-0 consolidations and rolling stock, but I have one return loop that has a 3.5 foot radius across a 10 foot long curved trestle 28 inches high. The locomotive will negoiate this curve, but with body mounted couplers, the cars can not as the couplers are short in length and bind and cause the cars to tip over. I can not increase the raduis of the curve as it would interfere with the gate leading into the back yard. This radius worked ok for all my 1:22.5 equipment, but ever since I started purchasing 1:20.3 equipment to eventually go F scale completely, it has been an issue. So I am hoping that someone can tell me if there are any couplers with longer shanks that will fit in the Bachman coupler Pockets that will solve this problem.
Thanks;
