After talking to Nick at Applied GMC and a local RV shop, I concluded that replacing the original GMC compressor with the Sanden unit Jim sells was the best course of action. Everyone claimed that rebuilds are losers. Although I like to do my own work, I don't have the tools to do A/C work, so I used a local shop. (ALED in Petaluma, CA) I was impressed with their work and the care they took.
Anyway,
Here's what you need to know if you're taking this on yourself.
In addition to Jim K's kit comprising the Sanden Compressor, adapter brackets, and two hoses, you'll need
1. To paint the brackets
2. An adapter for the high side fitting to convert to R134A P/N 409902
3. A new A/C belt as the old one is too large. The belt listed in the Vintage Air bracket kit is incorrect. One that fits is NAPA 257585
You'll have to clean and pull a vacuum on the A/C system, install oil, dye, and refrigerant, all of which I didn't feel comfortable doing myself. Because of the slightly different location of the new compressor, the heater hoses interferred and required repositioning and/or replacing.

Pete,
I found them a $1.50 cheaper from the Napa store online and locally than from the ebay site.
or
http://tinyurl.com/om83ekm
for the high side
and
and
http://tinyurl.com/o2nosyb
for the Low side
You need both for the conversion.

Cost of the project:
$650 to Applied for Sanden Compressor, hoses and dryer
$319 for fluids, fitting and belt (refrigerant, dye, oil, flush fluid)
$960 labor (work was underestimated, but Aled stuck with the estimate)
$1929 total
Wow, a lot, but I want my wife to travel with me again. She'd rather be home doing her artwork.

Thanks. Its good to get a ballpark cost for when you are looking at a coach where the dash AC is not working.
