I have just done the conversion, replaced o-rings as well as receiver-dryer.

Mine was bought at St. James VW in Winnipeg, it cost me $24.00 CDN. Thats
prolly about $18.00 US.

I wish I could resell them, but they need a license number from you to sell
any A/C parts, even O-rings, I kid you not!

Manitoba is totally Nazi with it's A/C rules, however, if you have a license
number from the US, they may sell you one, don't know.

Cheers!

Marshall
