Was doing to work on some freight cars this morning and had one set of M/T 1030 roller bearing trucks left so thought I would put them on this Athearn gondola. Well, I found that the screw from the original Athearn truck was just a tad smaller that the hole in the M/T truck. Anyone else run into an issue like this and have a suggestion for a fix? It's no big deal if they don't get upgraded as it has knucle couplers already. Thanks for any input.
