i had a few posts in my build thread but decided to make a thread for this, maybe someone will find it helpful when doing preliminary research. i purchased a new gen IV vintage air surfit kit for my 1975 fj40, with 2F , no power steering, and oem alternator.
my install is already complete and the system is working great, but ill try and recount my efforts. the kit is separated into three instruction installs, evap / compressor / condensor. i started with the evap box. the instructions are pretty basic and dont leave a lot of room for error so i will not go into detail. they involve removing your heater box and lines, and blower. then routing a few wires and installing the evap box unit and controls. the controls look great in my opinion. the box fits pretty snug up against your dash, and mounts in a few locations. you need to drills a few holes, and enlarge some existing bolt holes. you should have already drained the radiator and coolant system at this point, if that was obvious.. also you need to go buy some heater hose and a few hose clamps (i like the oem band clamps).
