I am looking for T supports for Thompson rod. Is there someone that sells these other than MSC, Grainger ($$$). Doesn't seem like that complicated of a part for as much as they want.
lee shafting, nook industries, nb bearings, pacificd bearing, all make functional equivalents. The parts do have to be flat on the bottom and parallel to the center-line of the shaft. I would guess NB is the least expensive.
