Thank you both. I was hoping to do it the easy way and find an exact replacement truck with an attached coupler from Bachmann, haven't heard yet. I have reamed a plain MT truck, waiting for one with a coupler to arrive.  Then there's the vertical issue, got to find some shims in my collection to fit the bolster to get the wheels away from the car bottom.  Hey, nothing else to do today on my to-do list, haven't checked hers yet.

I recently purchased a Spectrum tender item no. 89553 with the plan to convert it to a MOW tender.  This means replacing the forward truck (with the drawbar)with one that has an attached coupler so that it has couplers on both ends.  I didn't get any help from the parts person I spoke with.  MTL trucks don't fit the bolsters on this car.  Any ideas?
