I mean, you could just grab a working fridge that's newer then say, 1990 and swap over all of that stuff. I suppose that's what I was looking into doing.It IS possible, and horribly expensive. Like $1500 expensive, and that was before Trump started his little trade war with China. Talked to the shop that did a refit on my 1954 fridge with a new compressor about a similar refit for my freezer, and because they needed a new condenser coil, it had to be custom made, and the only people even willing to undertake the attempt were in China, and they wanted $3000 just for the coil. That did not include a new compressor, fittings, or any labor. The shop said that before the trade war, the same unit would have cost about $800.
