    If you haven't found them already, push-nuts for the cable pivot studs are available from AMK, B-10566. They always seem to break or bend beyond use after trying to remove once on. The two attaching posts on the defrost outlet also uses a push-nut, can't remember if it's the same size as the pivot stud.

    Ugh.

    I did a trial fit and there is no way in the world that I can get the heater box and/or blower motor installed with the inner fender in place. It just doesn’t seem possible. Is the front of the inner fender the battery tray? So I have to remove the battery and all attaching bolts on the inner fender well, the tire, and let it drop down out of the way?

    Who’s done it before? Come on save me some time. :)

    Sounds like I can leave battery in place and just lower inner fender. Hadn’t thought about it but maybe I should get new blower motor? Definitely don’t want to do this again...

    So you can barely squeeze an arm in the space between the inner fender well and fender but they key to this was removing the frame mounted support bracket. Once that’s out-of-the-way, and the inner fender well drops down a little bit, you can maneuver the heater box with the blower already attached into position. The rest is just bolting everything up.

    The white strip caulk that I purchased worked perfectly. It’s three wide and you can use it 1, 2 or 3 wide as it’s perforated and tears lengthwise. The 1 wide was perfect for the heater box which has a groove for the insertion of caulking. The caulk is tacky enough to stick to the heater box but not come off all over your hands while you maneuver it into position. Sealed the blower motor to box as well. So this portion of the install went pretty well and before putting everything back up I wanted to make sure that the blower motor works. Next problem.

    Ok So I figure I will hook up the blower motor switch and battery and make sure that the blower motor work before putting the inner fender back together. This plug has been hanging underneath the dash and I assumed it was for the blower controller on the heater control panel. However this is what I have in the back of my heater panel and it appears I’m missing a switch that should be on the heater control? Anybody know exactly what I’m missing and do they sell it separately? Hopefully I don’t have to buy another controller. 601FAA75-4A72-404B-A2DD-2EEDB6CA1012.jpeg F2F1C406-F2CB-4BF6-AF6E-890BD2031C21.jpeg F0768A95-7C9A-415F-B0C0-E8D631880356.jpeg
