Just look up conversions in general, I imaging there’s either YouTube videos or someone has posted all the steps with every little tip and trick for exactly that year and model on some site.

Releasing any of that into the atmosphere is “illegal” but if it doesn’t work then it was already all gone… right? I think so. A manifold and vacuum is expensive. The compressor is the big thing. You can run r134 through the original one but it isn’t as efficient and will eventually kill it, eventually. So hoses and fittings which are cheap and easy to do. Then just use the super easy Schrader valve cans to fill it up. Compressors run ~$500 I think but without that it can be done for less than $200, like $100 if you look around.

I can ask a few people but I dont think I’ve heard a r134 conversion including the compressor go for over a band.
