Does anyone have one to convert a standard Commercial set of gauges to a Nissan A/C system? I have access to someone'e equipment, gauges, freon, leak testing equipment, etc.. (and their knowledge =)) But I just need to find an adapter to adapt their gauges and equipment to the system on the G20. He said the gauges he has are a standard size so that end i shouldn't worry about (1/4" i think?), just the side that plugs into my system. I'd just go out and buy them but they are like $50+ for the adapters and you need two of them (one for the low and one for the high side). Anyone have some laying around they'd be willing to let me borrow (i'll pay shipping both ways, etc...). Thank you!
