I want to convert the AC system in my 90 K5 to an OBA system. I've seen write up's for York style, and for the long compressor style. But I can't find anything for the style compressor I have. I think it's called a "pancake" style, but I'm not sure. /forums/images/graemlins/dunno.gif If anyone has any links to a write up, it would be greatly appreciated. Oh, and I've already searched here. But maybe not deep enough. /forums/images/graemlins/dunno.gif Thanks.
