where did you find that odd thing, it's not from a 59 truck heater - got a pic of the heater? depends on which it is if you can use the "earlier" one, I suspect it's not a TF truck original but something some PO added in from some other vehicle

have you checked with this guy for rebuilding?

you could always get an aftermarket cable operated control from NAPA and mount it inline under the hood
