1972 Duster Build with my Daughter
GlenRay rebuilt heater core fits like a glove. The DMT kit gave you the correct white caulking for between the core and the back case (the front cover has a foam seal). It was dried out in just the time I had the kit open. I threw it in the garbage and got out the old reliable 3M Dum-Dum...
Don't forget the foam strip to seal around the heater pipes.
In restoring the visible plastic I used Herb's adhesion promotor and his dye. I like it for textured panels but not for smooth plastic. SEM satin black is still my favorite for smooth surfaces. Its spray nozzle is the best I have ever seen and it looks orange peeled when you lay it down but it flattens out and looks great..
Herb's paint.
Now in goes the first door which switches from heat to AC and to the under dash vent assy.
Now the door that switches to the defroster vents. See the piece of foam DMT give you so it won't rattle, just like the original.
This door must go in the cover first but here is where it sits in the housing.
In the cover it goes.
Now the AC section is bolted and and done!
