Filler went in good, bit tips went in smooth started them with the drill (little battery job & ran it real slow) finished with the nut driver only I screw up, the corner screws that come up from the bottom have less material than the middle, made 1- 1/8 inch hole in my beautiful grill.
ended with 2 little dips at the ends not too bad.
It was not an optical illusion bumper is a full 1/2" out more on the drivers side, loosened that first & had no play to push it back.

Passenger side

So I loosened the passenger side, it was all the way out, that had play to the rear, Pretty sure the whole thing should look like this.....................

So I pulled it back all the way out, 1/2" is better than 2 1/2" on one side & 1 on the other!

Unless I get crazy & pull the drivers side brackets & elongate the holes this is it for now!

Moved on to the heater cable, when I got to the point the whole drivers side of the dash had to come apart to get that control out I tried from underneath, after much wailing & gnashing of teeth (thanks Jass) I finally got the screw in.
Not liking the adjustment, it will only go full open with the cable completely out of the clip, I have it barley on the edge & she's about 1/4" away from the stop, it does go full in the other direction.

I got lucky & fount a couple of clips that hold it down from my air vent leftovers from the 73.
The grommet was smaller than the whole, was gonna pull my old grommet & do it from outside, Not ever pulling that cable off the control again & saw it was the same size.
So I put a big wad of GOOP glue on it & cable tied it to keep it straight till the glue dries, can't see it from outside which is probably a good thing.

so last thing before I lowered the front was that boot, not too bad, took the 2 nits off that side & had just enough play to worm it off, stuck the boot on & retorqued em.

Of course I forgot to tighten all the front valance bolts, don't have to get too far under for those I hope I can get to them all without lifting it again!
