Project 968 will need a/c work soon. Suggestions? Griffiths compressor? Conversion Kit?
Thanks,
Gregg

Going to be doing the same conversion in the next week or so ill get back to you after then, but it doesn't look too complicated. Its certainly is more affordable than a new oem compressor. Have you considered a used oem compressor?

I bought a rebuilt compressor off of eBay last year for $130, which included a 1yr warranty and was pre-filled with the correct amount of oil. Bolted it up, boiled the system for a couple of hours, then charged it with 134a. I only installed the LP side 134a fitting - the HP one that came in the kit I bought at Advance Auto didn't fit.
Prior to the eBay compressor, I had been looking at the 944online and Kuehl conversions. I read some not so favorable reviews of the 944online kit and the Kuehl kit, with condenser, was $1k.
I have less than $200 in the whole system (didn't even replace the receiver/dryer) and it blows plenty cold. When this compressor dies, I'll do the same thing again. $150 for the compressor (shipped), $12 for the R134a fittings, $25 for the R134a. I already had the gauges and vacuum pump.

Hey Gregg, I'll be in town Friday through the following weekend, if you need a hand installing parts. I'm certified for automotive AC and can buy r12 if you decide to stick with it.
Older systems can have dried or shrunken o-rings at just about every fitting, not just around the compressor. So you might have your work cut out for you. Last summer I used Ed Pimm's vacuum pump, some cheaper r22, and electronic leak detector refrigerant to track down all of my car's leaks before wasting a refill on r12. My problem turned out to be cracked welds around the condensor line fittings, which I still haven't repaired.

I did a complete conversion with new griffith's condenser and compressor last year and can't complain - not an easy job though to do right. If you're buying the griffith's compressor and hoses be sure to mention the fact that the low-side elbow fitting needs to be fabricated with the fill coupling 90 degrees to what griffith's had been providing for years. I don't know if the 968 is all that different from the S2 the kit was developed on, but on my 968 the "standard" fitting wouldn't fit. Charlie was good enough to make me one that did.
