Last spring or over the summer I had NWSL make two new sets of wheel sets for AM SD60 because I had purchased two AC/hirail at a flea market. I sent them an axle so that they would know what they had to duplicate. They came back with the bearings too wide to fit in the gear tower castings. They were very good about it and fixed the problem promptly.
So there is confusion to go around with the different generations of AM drives and bearings. There is way too much side-to-side play in the center axles of the Train Masters and SD60s. Certainly no need to worry about blind flanges on 6" radius ;) track.
