What A/C compressor is it? R-22 to R-410A, is it necessary?

The compressor in the image will be a boat anchor in the near future. I wanted to replace it but I wanted to know if it's necessary to switch over to R-410A. If so, are there kits available supplying the parts needed? i.e. a different condenser, evaporator core, possibly, orifice tubes, etc.? Thanks for any and all input. :)

First off, it's R134A. I'm sure you could find the parts necessary, but I'm not sure if there is a kit. I am not familiar enough with the older cars to be able to tell you.

There are adapters you can buy seperately to convert the R12 fittings to r134a. There are also kits that come with the same adapters as well as a few cans of refridgerant, and a gauge.

Provided everything is sealed and working correctly, you technically don't have to replace anything. The key is to remove all of the old stuff and check to see if it can hold a vacuum.

The filter drier, aka accumulator should be replaced though.

R22 was used in residential AC systems. Been banned now for years. There was a recent article in "Chevelle" magazine on how to update the old A6 - six cylinder systems (which is the type in your photo) with all new modern direct bolt-in components. They refer to OLD AIR PRODUCTS at www.oldairproducts.com and Mark's Air at www.marksair.com. I have not made this swap so I can't vouch for it but, it might be worth a phone call or calls. I have checked some of the prices on these components and this isn't a cheap conversion but, it might be your only choice if you want AC. Thanks!!!

Parts you can keep:

Condensor
Evaporator
Hoses (more on this later)

Compressor...get a new or remann'd. Your old one could work, but it might not for much longer.

Things to change:
Filter/dryer/accumulator
Orifice tube
All O-rings...ALL OF THEM.

Now then, on to those hoses...yes, there are adapter kits that will allow you to keep your hoses and use them with 134a charging hoses. HOWEVER, they tend to leak. I went through 4 kits before I was able to come up with a set that didn't leak out. With that said, I would buy new hoses with the fittings already on them. Changing out all the o-rings is very important, as all the older R12 orings cannot seal well against the higher pressures R134a needs. Adding in a cooling fan that comes on with the compressor will help greatly.
