ARQ,for some reason I can't P/M you and your e-mail address get bounced back to me when I tried to reply to your e-mail you sent me. Anyhow here's my response to your e-mail. ARQ, The only Old Air Products piece was the POA eliminator. I got everything from Ricks pickup parts. http://www.rickspickupparts.com/ He was very helpfull.All the parts came to about $600.00 Then I had lines made which was another $300.00(I think I got ripped off there) I've since got a tool that allows me to make my own lines and have redone the lines I had made. I got ALOT of info. from http://www.ackits.com/ It's a great resource and they sell parts at a great price as well. My A/C conversion was a learning experiance and I spent alot of money learning how to do it the RIGHT way and not skipping corners.I also wanted to know how to service and maintain my A/C system,that's why I decided to buy all the equipment I needed. If you just want A/C and leave the servicing to someone else I'd install an aftermarket unit like what Old Air Products offers or Vintage air.They both make bolt in kit's for our year trucks http://www.oldairproducts.com/shop/index.php http://www.vintageair.com/ If tou decide to go the route I took I'd be more than happy to help anyway I can. Also,if you need lines made up I'd be willing for just the cost of the materials.The lines I made are still leak free and performing well. Later,Bob.
