I had to do the same thing for 64 pieces of rolling that had couplers mounted to the trucks (talgo trucks). I also replaced all the plastic wheel sets with Walthers Proto 2000 metal wheel sets. This hobby gets expensive when you do upgrades. I also made some wheel pickups out of some thin copper strips I salvaged from an old computer and lit up an REA (Railway Express Agency) mail car and put LED strip lighting in it. I used bright white LED strip (about 12 LED's that can be cut apart at every 3rd LED) and it was too white so I took the coach apart again and painted each LED with yellow acrylic paint. Now it has that warm glow. I remember making a bunch of shims to go under the draft boxes. On some of the coaches I had to drill through the weight and ran the 2-56 tap through it. Those will never come off. And I did the same thing you did and used a 2-56 screw through the center of each coupler to keep them secure. I also placed a small drop of CA beside each screw head before painting them to make sure the screw never backs out. You can use those pieces you cut from the trucks as shims too.

Thanks for watching. Yes, this hobby is expensive when you start upgrading and making improvements to your layout.
