This forum has been very helpful to me.  As a means of documenting some of what we have done and to help others avoid some of my mistakes I thought I would post the installation of a vintage gen II mini AC system.     Background: My son and I are restoring a 1973 240z.  We call it the bucket, as there was a significant amount of rust that had to be dealt with and our other choice – Money Pit was already taken.  We are changing the color from 113 avocado green to mango orange,
