Default 1970 AC heater control valve

Where exactly does the heater control valve mount? Since I didn't take the car apart, not really sure where the original mount was.

You access the valve by removing the passenger side "egg crate" behind the front wheel well. The valve is mounted in the opening. Often it's been replaced with a non-mounting one and is just floating in there. The vendors have the proper one. MelWff's link shows it.

Remove the splash shield first (4) bolts, 2 behind the rocker trim and 2 underneath. Pretty sure you'll have to do this to remove the louver anyway. Be extremely careful with the louvre there are 2 screws outside and a bolt that is part of the louver mold held on by nut of course.
PB Blaster this as much as possible and don't hurry, it's very fragile (How would I know this ? ).
An assembly manual helps but you just have to take your time to get through it.
Good Luck

Remove the eggcrate and you can get right to it.

P.S. If you've not removed an 'eggcrate' vent panel before, finding that nut (on the inside and angled downward) with a socket on a long extension is a bit of a trick. It's either a 3/8" nut or an 11/32" nut [don't hold me to that!]. You might want to shoot a little PB Blaster on that nut/thread before you wrench it.

Use a 3/8" six point socket is best....so you do not take the chance in rounding off the corners of the nut.

If you use PB Blaster...do not shoot it on the nut. Spray some in a cup and apply it manually with a Q-Tip. This way you are not possibly spraying the PB Blaster on your fiberglass and have a saturation issue down the road. If you do not have PB Blaster on hand. You can make a 50/50 mixture of automatic transmission fluid and acetone. It is actually better. If you do not have acetone..I read that there are other liquids that can be substituted for acetone. Google it and you can find what else you can use....such as ...if I am remembering correctly...mineral spirits, kerosene come to mind.
