Great - glad it worked out!
I used sure marine to replace the rheostats inside the stove (including the shafts onto which those knobs mount) ... the contact layouts were a little different, but the paperwork explained what was different and how to wire them. That was a couple years back and the stove still works great, although I don't use it all that much. The originals had rotted inside and locked up.
