I'm sorry, I can't remember the 2790-HVxxxxxx part-number for the slider knobs. Red Dot has a similar knob, RD544500, but of course I'd rather look up the truck by model and serial, get the 2RD heater assembly number and grab the correct 2790- knob number from that breakdown and supercede forward from there.
