Restoring my abandoned heating system. Removed the heater control assembly and found all the cables in good shape, all the doors work in the heater box, but there is a flat plastic grooved part the cables attach to on the heater control assembly. This black piece of plastic mounts on the top of the heater control unit. It is elliptical in shape. The cables move it in an arc when the selector slider knob is moved. Mine plastic piece is broken.
Will take just the plastic piece the 2 cables connect to, if someone has one. Will take the whole assembly, if need be. 1969 is unique. 67-68 won't work.

Also need the 69 blower motor switch. 67-68 is different.

Thanks.
