Just read your post and I had posted the other day about installing an entire unit on a '79 244 that never had a/c. Would it be possible to get the entire system from a late model 240 with the 134a system and would I be able to pull the bracket from the late model and put it on the '79. I would do away with the rotary compressor if I could go with the newer style compressor.

Thanks.

Used vs new vs rebuilt.

The shame of it all is the warranty is about the same on all of them.

I have a pup unit out of a 90's R 12 model that was hit in the rear. The dang system was still charged and I almost burned my dang hand when I discovered that.

The risk is how long will that used one last. I have had the donor part running strong for three years now and a little over 50K miles. Not bad for a $25 price tag. I might now want to use one that did have a charge on the system however.

Rebuilt ones run $150 each around town and the new ones go up over $300.00.

Regardless of what type of working unit you get, replacing the expansion valve, cleaning out the lines, and installing the dryer right before you close, and making sure your system is tight before you start adding coolant are the keys to getting your cool back on successfully.

Good Luck,

Paul
