kip,

So, buying the largest condensor you can get, paying hundreds and the hassle of changing compressors. What will that cost?

Now how much is three pounds of R12? I'll let you do the math.

Most conversions end up as false economy. People spend hundreds of dollars to convert to save $50 or so on their refrigerant. I'm not a very smart guy and I learned my math in the fifties and sixties before the so called "new math" came along. But I fully believe that my calculations are correct.

Let's say you need a new York. You can get a quality rebuilt York for $100 exchange, r/d maybe $50, R12 $50 plus $15 for a 609 certificate if you don't have one. Now replacing the condensor alone and making the hoses for the job will cost more than that.

I love a York compressor system. The compressors are cheap and durable as long as you don't allow liquid to hit the reed valves while charging. Many of these systems have service valves rather than Shrader ports which adds all sorts of added features and possibilities when servicing.

Also your old 115 car, may very well have stratoflex lines that you can actually repair by unthreading them, cutting a little off the line and threading it back together.

The York is less efficient than newer units so it will soak up a few horsepower. So what, I doubt that you are using this vehicle for a race car.

In the seventies my wife had a 114 250 and I had 114 230 stick shift. Both of them had stratoflex lines and York compressors. As far as I'm concerned they were the best, most durable a/c systems I ever had in a car. Not only that, they almost made ice cubes.

If that car were mine, I would find my leak or bad component, flush it, replace r/d and do whatever it needed to put it back like it should be. When I was done I would be happy to know what a great system I had.

Good luck,
