    No rust in the whole darn car except the left rear window channel. Needed to polish it out, do some welding/grinding. Then rust treatment with KBS coatings.

    The previous hard work to keep the A/C finally paid off and works beautiful. It did not come without some snags along the way. I was able to use a stock accumulator that has the removable line in the bottom. I purchased all of my A/C fittings and hose from www.coldhose.com - Super nice and helpful people. I sized up the hose and clocked the fittings and had them crimped as I don't have the tool to crimp A/C hose. The first problem was that the high side was excessively high to the point that the relief valve vented. (no it was not overcharged, I charged with my A/C scale, 28oz). Turns out that the original caprice condenser houses the orifice tube. So in additional to the stock orifice tube at the evaporator, I also had a 2nd one in the condenser. Once removed, the pressures settled as they should and I was putting out 40º air at idle with an ambient of 105º which was perfect. The PCM properly controls the clutch as well as the primary and secondary fans. I also polished the new accumulator before installing. I'll post some photos of the A/C hoses and routing later.

    I also had a successful wrecking yard run. Turns out my caprice axle was missing all of the parking brake hardware which is long discontinued and searching ebay was of no help. Every caprice I have found in the wrecking yard had drum brakes. I saw over the weekend that their inventory had recently received a caprice and the photo showed the wheels common to the 9C1 (police) which I knew would have rear disc brakes. I scrambled and made my way and to my surprise the rear axle was still in the car. After popping out the axles, I removed the entire backing plates from both sides, hardware, etc and $26 later had the final pieces.

    Did you ever take pictures of your a/c hoses and routing?

    As far as the AC goes, I still have some detail work to perform but works fine. Since the orifice tube is located in the outlet of the condenser, I've insulated the high side return but I don't care for it. I'm going to use something else to insulate the line. When summer comes around again, I'll see how it performs without it.
