Keith, Some thoughts on the A/C issue. My C has factory A/C and I added rear A/C from Old Air Products in Fort Worth. I also added a 1100 cfm condenser fan and a trinary switch to protect the Chrysler compressor. I'm running R-12 as refrigerant and have factory Solex glass since it was a factory A/C car. The Model 900 HVAC system parts are extremely hard to come by and the underdash componentry is a "Rube Goldberg" scenario of Chrysler engineering at best. Fortunately the oil mechanisms and solenoids all work. Many previous owners found getting the A/C system to be cold a venerable money pit with tepid results. I spent countless $$$ thousands getting replacement parts , etc. to get it keeping cold and working to parameters. Starting off with anything short of NOS will be a nightmare of a Stephen King novel proportion. George McKovich installed aftermarket A/C in his non-factory C and is very pleased. Bill Woodman installed a '56 rear unit with a Sandin compressor and is very pleased. Merle Wolfer is working on a factory unit for his D. Jeff Carter knows these units thoroughly and may be able to get you headed in the right direction if you must have a factory unit. My advice would be to contact George McKovich and persue that route since you don't have a factory A/C car. My 2 cents worth. 300'ly, ROB KERN ----- Original Message ----- From: keboonstra To: Chrysler300@xxxxxxxxxxxxxxx Sent: Tuesday, October 27, 2009 12:34 PM Subject: [Chrysler300] 1957 Air conditioning OK Folks, our '57 300C has sat in the barn way too much in the summers just because I'm too spoiled rotten to ride around without A/C anymore in a car that doesn't have a flip top. And besides that, it needed a few improvements that are long overdue. After owning it now (for the second time) for 26 years, I'm finally taking care of a lot of the things I should have been doing right along. I'm putting in seat belts, re-installing correct carbs, finally putting on that right side mirror, fixing up the armrests, and maybe I'll throw a set of WW radials on it so it can safely hit the road. So now I would also like to install a complete original A/C system, and I don't know where to start. Who out there might have everything I'm going to need to accomplish this (both the parts and the knowledge)? I know this won't be cheap, but in my view it will add that much long term value to the car. And it will add immensely to our pleasure in heading halfway across the country for a meet. Who's got parts or ideas for a starting point? Your thoughts? Many thanks, Keith Boonstra Holland, Michigan [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
