Is that a thing? Let's say i have my eyes on a car that didn't come with an AC. Is it possible to Frankenstein it from another car or straight up get an after-market one or maybe just build one yourself ? And i Know it's possible, because everything is possible and it's a community of people who drive coffins made out of scrap metal on the mountain roads. The question is HOW is it done and if anyone actually done that before?
