Ken, I have done it on ATC cars, but if you have standard AC (and I think you do, as yours is an early car), you'll just have to plow a new furrow using the FSM. It is a nightmare on ATC cars, I agree, and probably not much better on a standard AC car, but at least you don't have the DUAL heater core to deal with (I don't think). I did find that removing the front seats and getting a really good drop light was a big help.

It appears that when Chrysler built this car, the first component they started with was the heater core and then built the rest of the car around it! I have read the service manual, and its 26 simple steps to remove and replace this thing are a bit intimidating (i.e., "Adjust electrical by-pass switch operating arm to have .020 to .060 operating clearance between operating arm and actuator rod." [I can see myself making this adjustment on my back under the dash!]). I would appreciate any war stories from people who have actually done (or maybe just attempted to do) this. I may let the next owner of this car fuss with this. Ken Miller ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
