I hate to continue sounding like a newby but to Plymouth products I guess I am. Every time I try to do research to find a part things come up that have no relation to what I'm looking for. Trying to find a speedometer cable for a '74 RR produced things that might fit other models but not a '74 so I finally selected a generic one that I hope will fit. I purchased some reprints of the original shop manuals and electrical schematics but they cover several different '74 Chrysler products with no specific drawings of installations. At this rate I'll never get this car back on the road.

Now I would like to find the correct heater temperature control valve and how it's attached to the car. I have all kinds of offers from vacuum controlled to thermostatic controlled but the one that's on the heater hose in the car apparently uses a control cable and there are only two small holes in the fender that don't match any of the holes in the existing valve. If anyone has a picture or diagram of how it's attached and if it's correct for a '74 I would appreciate some help.
 
go to my mopar .com and see the pdf service manuals for free. you might want to join the ... for b-bodies only .com for more info you might need as a lot of cross-over on parts and info.
 
I bought both reprinted copies of the service (shop) manuals but they don't go into detail or have illustrations of the heater control valve. Since the service/shop manuals cover every body type developed by Chrysler in '74 the detailed drawings show locations of various parts but not how they're mounted or operated. The interior for the R-W body style is shown and how the operating cable is connected at the dash control but not the engine compartment valve.

I've been on every Chrysler body style forum I could find but apparently no one has ever addressed the subject before. I appreciate the referrals and advice and I'll continue looking maybe I'll find something. The last interior drawing is OK but my car has AC and except for the temperature control location and such the air vents don't apply.
