sounds to me like Mike was asking all the right questions.....sell it and by a Ford?!?!?! C'mon! I mean really!

Regarding the AC, I converted my 300D to R-134 by replacing everything except the evaporator. I would follow what Larry said, however I might differ regarding putting old hoses back in....after going to the trouble of taking it all apart, when I did my car it was tough for me to put back original parts knowing that anyone of them may fail soon. On the other hand I have heard of quick and easy conversions that worked.

On mine, I made a few modifications in an attemp to improve cooling....I replaced the original condenser with a universal parralel flow...i put in the biggest one that would fit, and had to have some custom hoses made to make connections. I also wired the aux fan with a relay to the compressor circuit so it would go on whenever the compressor went on (not necessary when tooling down the highway, but helpful during stop and go). The system works very well, even on humid days in the 90's...reasonably well for short hops. Central vent temps down to 41 deg F when fan on high and max cool. The real limiting factor is the size of the evaporator..even if you could maintain constant evap temperature of 33 deg F, you would have limited cooling capacity during very humid weather due to its size....nothing like the the big evaporators on R-12 systems in big older american cars that blew snow!!

good luck,

mark
