Since most of you guys have tried some of this before:

I have an old York compressor in a 73 mustang. It finally gave up. A rebuilt compressor is only $120 that I could convert to R134 or I could spend $450 on a R134 set up. I would really rather go the cheap route. Has any one done that? What do you all think?

 

You could just replace the York and charge it with a product like this: http://www.freeze12.com/index.html

 

My old compessor bit the dust last week too. I ponered just replaing the old York with a 136 bux replacement, but was advised by some pretty sharp cookies to go with the sanden swap. I found the kit for less than 500 bux, so will be going that route because the sanden is much quiter and efficient. I have grown very tired of the rumbling and shaking from the old York.

 

Considering R12 is pretty much in the controlled substance list these days and not being produced any longer. I'd pony up the cash now for R134a. Pay now or pay later if your R12 system needs more repairs down the road.

 

Who were the "pretty sharp cookies"?

 

Hutchamatic for one. Here is the thread from a few days ago. Hutch and I PM'd back and forth to work out the details.

I was just wondering. Freeze 12 works well in vehicles that don't have compressor update kits available. There is no conversion and it blows just as cold as r12. I used it in my 69 P 1800 with a York compressor and it worked great. I guess as usual it comes down to how much coin you are willing to drop and if you want to keep the original look.

 

I converted my old York to R134 and it did OK. I was just checking. I would really like to hear from some foolks that did both.

Soaring I watched your thread. $500 is a bit of coin. Especially when the other is only $120

 

Agreed, it ain't hay.... Like I said, I was very tempted to just put a 130 dollar replacement compressor on, but Hutchamatic talked me out of it. You certainly aren't going to hurt anything buy putting the 120 dollar one on. I did the change over to 134A with my old York, and it did just fine until recently where I guess it is just flat wore out. It rumbles, vibrates, rattles and makes all kind of noises. So, it's time she went to compressor heaven.
