No, I didn't notice this here. I have a couple of spare pairs yet to install.
I've been working in so many different directions lately that I may have missed this?
I converted an Atlas articulated auto carrier to 2 rail a few days ago and had to go thru some extra work to set up the middle truck. It has a different bolster post and I had to tear apart the whole truck to swap out the bolsters.
On the ends, the trucks I got fit right on. I can't remember what car exactly they came from. I believe they were from a trade? I went to use a newer set and they seemed to be the same modern version with the narrower side frame spacing, so I used the traded ones.
