Ford A/C retrofit package

I have been searching the forums to try and find some answers to my A/C problems, and have seen several mentions of a 134A retrofit kit from ford that includes a new, more effcient, condenser, dryer, accumulator, etc. Does anyone know where I could get one of these, or get more information on one?
I had my car converted to 134A by a mechanics shop last year. The A/C is pretty cold, but while idling it spits out hot oil from the compressor. Maybe the shop overfilled it. I have read several times that the stock condenser doesn't work well with a 134A system. I have also read that I may need to replace dryer and accumulator. My condenser is pretty beat up from rocks, etc, and if I am going to replace it, I would like to replace it with a better model. Does anyone know a company that makes better condensers for 93 mustangs? Thanks for the help.
 
I replaced the accumlator/dryer hose on my 91 and had the rest of the system checked. I still have the R-12 and since replacing the hose it's been working good. I got the hose through Autozone for $89.99. You might want to give Hose Wizard a call for condensor/compressor issues reguarding the 134A kits (1-877-252-3364). I've tried finding info on using a different condensor, such as one from a 94+ stang that doesn't block airflow going to the radiator. Good Luck!
