'84 A/C Refurb help

[bazthespazz]

I inherited my '84 about 6 years ago when my father-in-law got too old to drive and the A/C has never worked. I jumped the pressure switch and got the compressor to spin up and the bearings sound like they're grinding rocks. I was thinking about replacing it with a rebuilt R4 from Four Seasons and trying to charge it myself with a kit from Enviro-Safe. What else would I need to replace before I try to recharge it? Opinions???

Here are all the A/C videos I have done.

Honestly, Just do what you can without the specialty tools and then take it to a shop. It's cheaper than buying the tools, parts, and chemicals in the long term.
