I don't recall the change point offhand, but TS39781LO originally had the
earlier type, with the shorter shaft and the fixing screw for the knob. The
later ones use a "push button" to retain the knob, like the rest of the
switches.

TRF has them listed in stock, P/N 509735, $5.75

You might want to be sure that's a heater rheostat and not a dash light
rheostat. I believe they have different resistances (but don't know any
values offhand).
