I have been looking to replace my R12 AC that doesn't work anymore with a new 134 AC system. After looking around the internet I found the Classic Auto Air unit designed for my car as a replacement. Has anyone had any experience with this unit? If you do it right will it do at least as well as the old R12 units? Seems like getting the hoses through the rocker panels along the side would be really difficult. Anyone have any experience with that? The cost of the kit is about $1700 which includes a new fan unit. From what I read I might have to add a relay to get enough power to that fan. The $1700 would be a small price to pay for some cooling in my much beloved car. I have upgraded many things on the car so they works the way they should but the AC is still a NoOP.
