gt3r,
I'm going to keep the ATCO crimping tool and I'm not really interested in renting it out as I will using it through the summer (it's one of my contributions to our 911 group here in the Santa Fe/ Los Alamos area). Due to the heat, there's always an interest in getting a 911 A/C working and the R134a conversions seem to be doing okay and I expect we'll be doing more of them as the summer progresses and again next summer. The company in Dallas I bought the crimper from had several; I'll see if I can locate their address/phone number and post it. The hoses and fittings came from
www.automotiveacparts.com They sell #6, #8 and #10 barrier hose in 12', 25' and 50' lengths plus typical fittings (barb, beadlock, o-ring, flare, etc.). I also purchased a new expansion valve from them. Prices were very good and service was good. When making new hoses I recommend one convert to o-ring type fittings where ever feasible (compressor and receiver/drier) as they are much less leak prone. Of course to retain an existing condenser and evaporator one has to put flare fittings on their mating hose ends.
plain fan,
My unit doesn't have a return from the driver's side nor from the tunnel. The nozzle from the tunnel is sealed with a rubber cap before the evaporator/blower is installed. In my '76, with my kit; return air is pulled behind the passenger side floor board and then into the evaporator. There is a gap on both sides and the top of the floor board to allow air to enter.
emcon5,
The NAPA receiver/drier is somewhat generic but can be made to fit if one is willing to flip a hose around, install a bigger hose clamp to secure the r/d and unscrew the installed pressure switch and replace it with a plug made from a 3/8"-24UNF hex head cap screw. It also come with adapter fittings which allow it to be used with flare or o-ring type hose fittings. The NAPA unit readily replaced my recevier/drier since the system came originally with a similar diameter unit made by Modine. I have yet to find the longer but smaller diameter German OEM Behr receiver/drier for less than about $90. If one has big tires and/or a power antenna one may need to stay with the Behr type unit. I have posted the NAPA part numbers in a previous thread:

I have more images of the evaporator/blower unit and the receiver/drier and right front fender hose run; I'll post them when I have some more time.
