Hello Mike, Can't help with a lead on someone to assist you on a conversion. My advice is to find and repair your leak and stay with R12. You can still find R12 on ebay and Freeze 12 is still available as a substitute. I just restored the AC in my 78 Eldorado and used Freeze 12. I converted it to 134a once and the higher pressures blew the old hoses. When that happened I bought a new compressor, purged the system and went back to R12. If you need a source for Freeze 12 contact me, I just bought a case of it (12 cans) for $159 which included shipping costs. You may find it cheaper than that but my source had quick delivery, I ordered at 9AM one day and had it by Noon the next day and the source was not local. Good Luck, Rod 10921 --- On Tue, 6/7/11, Mike <cambpd@xxxxxxxxx> wrote: From: Mike <cambpd@xxxxxxxxx> Subject: [DML] R12 to R134 Conversion Help To: dmcnews@xxxxxxxxxxxxxxx Date: Tuesday, June 7, 2011, 10:22 PM Is there anyone in the Maryland area that I could get with on a weekend to help me convert my Delorean R12 a/c to R134? I've done all my own work on my car, but am afraid to tackle an R134 a/c conversion. Last fall I drove to PA. and had some welding work done on the frame, in the rear and up front around the right fender. On the way back to MD the a/c got weaker and weaker and finally shut off. Now it seems I have a leak somewhere in the R12 system and am thinking that it should first be converted over to R134 before trying to troubleshoot the leak?
