I do not have the time nor will power to build my own. I am looking for a kit like this:
Amazon.com: Air Products Air Conditioning Conversion Kit: Automotive
Just installed on my 735i and works fantastic. I really would not like a kit full of hoses, the compressor, etc as that will just jack up the cost. I want only the bracket as I will build my own hoses and purchase a compressor on my own. The place in E. Texas (European Cooler Air) makes one, but the kit is $625 + shipping... with bracket and compressor only. I am hoping for a price around $200, but if not I will end up going with the ECA place.
Found this for you W123 guys...
