    Hey all,

    So a little while ago I sent all my factory AC bits (minus evap box) to board member MuscleCarz for cleaning, testing, and re-calibrating for R134. Everything came back and looks great. In the interim i cleaned, sanded, painted (with clear coat only), and repaired the evap box.

    So I am ready to assemble the box and internals at this point. While I was in there (engine and front clip are off), I removed the heater core box as well. I have yet to crack that and start the cleaning & rebuilding of the core box. Actual box looks to be in good shape, but I will know more once I get into it.

    My question is, how do you seal the evap box where the evap lines come out? I have that black sticky tape stuff and all seals, but is there a certain method to apply it?

    Pics to come when I get home and have the time.

    Thanks for any and all help!

    Scott

    Hey Guys,

    So I am going to tackle putting the AC Evap box back together over the holiday weekend. Does anyone have any pictures of how the Valve Expansion Bulb attaches to the evaporator hose? I think it is with some metal clamps but cant seem to remember. Also if someone has a pic i can dig through my boxes of parts to see if i have those clamps. What other options besides the factory style clamps can i use?

    I am in the process but haven’t installed yet. I got one of those foam seal kits from TPP and some 3 M caulk strips. I also picked up some of that AC butyl tape to wrap (red circle) the tube after it comes out of the AC box.

    The third pic is something I found online and I’m trying to match that.

    Well Scott, I can't help you but I am surprised no one else can. I did my digging for heater valves online looking at pictures, utube, chevy/BOP sites, etc. I still didn't get it right but at least I know what it is supposed to look like! Contact oldairproducts, maybe they have some advice.
