This is marked as a Truth #31761A but every potential source that I've found doe NOT have the offset mounting tabs. According to Truth's literature, the wheels should be nylon because I suspect the track is aluminum. Mounting hole spacing is 5-3/4", max body width is 11/16".

Hello,

Take a look at our 81-018 roller and see if its measurements match up to yours. Thanks for posting!

The dimensions match up EXCEPT that the 81-081 does not have offset mounting tabs. Furthermore, the 81-018 has steel wheels which are not recommended for an aluminum track due to galling resulting from frequent movement of the hard steel rollers on the softer aluminum track. Truth's 61761A's roller assembly comes in at least (3) different versions (all stamped with '61761A'), none of those that I have found have offset mounting tabs.

In that case, I think you might find the 81-170 to be a closer replacement option since it has the same offset tabs and nylon wheels you'd prefer. Take a look and let us know if you have any other questions.
