Ac conversion

I did nothing other than pull a vacuum and put R134 in them in multiple cars over the years. Seems to work just fine.

I added factory air salvaged from another car to my cuda. Replaced the drier and expansion valve with factory replacements. Dumped the oil out of compressor and replaced with pag oil. Blows so cold I have to turn it down.

Not saying replacing other stuff is not better, just not necessary.
