I can rebuild the whole damn truck and get stumped on A/C. Thanks again.

Most people go with 134a because of cost and availability. A can of it is like $6 at Walmart. R12 needs to be sourced. But its readily available on ebay. I often see it on craigslist also. cost is going to range but I usually see a can for $15-$25. If you are not planning on charging it yourself, then you would have to find a competent shop that does r12. With 134a there is a shop willing to charge it, on every corner. Sanden type compressors are tried and true, can be had for $150 or less even in chrome but you cannot use factory hoses and brackets. Aluminum A6 replacement is half the weight of a steel a6, just as efficient as a sanden, and also draw less HP. There is a vendor selling a chrome a6 replacement for $359 on Ebay right now.

It may come down to whether you have to have a factory appearance or not. To me it comes down to ease of installation. Going with an a6 replacement makes it a bolt in deal. No need to have custom hoses made. Not a big deal for me because I have a crimper and can get hose/ fittings right down the rd and inexpensively. But some guys would prefer not to deal with this. If you really want the sanden then I would suggest you call one of the aftermarket ac companies like Old Air Products. They can sell you an under hood kit but it will be a little pricey because they've done the hard work for you. So the cost between the two style of compressors becomes a wash. As far the poa valve, they all work the same. its just the orientation of their fittings is different. I would have it checked out to make sure it functions correctly first before I charge that system. There are write-ups on how to check/ recalibrate it ( will involve a set of gauges)online or you can send it out to have this done. If you can't do it yourself, you can send to me and ill check it for you. No charge but you have to pay your shipping to and from. I rebuild them all the time. Here is a picture of an under hood system I made up for a customer out in NY. Its pretty much everything you would need other than brackets( he needed BB brackets which I didn't have) and the ac box which you already have. I would also the piccolo style condenser in the picture. At the time, I didn't a true parallel flow condenser which works a little better. Also a few pics of a poa rebuild. The last pic just shows the cycling switch along side two poa valves. I would stay away from it as a lot guys complain about them. You can do a search on here to see for reviews on them. I mention it because if you contact places like old air, they will try to sell you one.
