Larry:

If that's not the speedo cable clamped to the bottom of the brace for the dash, what is that armored tube?

I didn't have any trouble, but I may get the hooks anyway, the wire is kinda big. No marks, though.

Vent is held in by a screw on the right side visible when you open the glove box door, and by a spring clip top and bottom on the left side AND a screw hooking the closing knob to the flap inside. Unscrew with a 4mm allen through the front of the vent, remove the screw on the right, then use a small Torx or similar to fit into the hole in the spring clip, visible about half an inch from the side behind the vanes in the vent. Pull the top one down about 1/4" while pulling on the vent and it should stay out, then lift the bottom one up the same way and the vent should come out easily.

If you don't take the vent screw out, the vent won't come out. Going back in, line the vent flap fitting (white plastic) up with the screw and screw the screw in until the vent will close completely with a slight preload.
