Review:
Since I use MTL couplers as the standard on my N scale, converting the last of my Bachmann rolling stock was my next project. The results are great! I chose the MTL medium couplers on the trucks. They look like the original couplers although that appears a bit long.They roll just fine on my 9.5 radius curves without a problem. To install these trucks and couplers in place of the Bachmann trucks and couplers, I found it easiest to hand ream the pivot hole in the MTL truck with a #26 drill. That's just a tiny bit larger than the hole and easy to do if you work carefully. I would not recommend a motor driven drill. Hand work allows you to feel the work (and the plastic is soft enough). The Bachmann screw holds the new truck just like it held the Bachmann. If the truck doesn't pivot as freely as the original, hand file the hole a little more with a round jeweler's file. They track and couple well and look more prototypical too. They are a little harder to visually re-rail without the shiny wheels, but the MTLs look much more realistic.
