Sorry Kent, I didn't look close enough at that offering. It was inside their 34-46 section.
Jerry is correct that the square shaft (or the hole in the latch) could be worn. The handle is an easy fix, but it's a bit more difficult to weld inside a square hole. I built up the handle shafts on my 51, but wound up installing repop outside handles because the originals were pitted a bit.
