Shoddy work, maybe by GM

[71CHEVYSHORTBED402]

Granted these are built very well, but every very now and again I see something I wouldn't do, and sometimes it's by GM. For example, as I'm tearing into the cab recently I've found, all for the dash panel:

Glove box door latch plate. Everything is drilled for screws, but no screws. Works anyway. Unless that has to be removed for the glove box liner, and I can't imagine it would, then has to be factory.

Ash tray bracket. The two screws are missing for the top. As for the bottom, one screwed in from the bottom and the other from the top. Could be from a mechanic. The more I see from the guy I was using, the more I see he wasn't who I thought he was.

Emergency Brake. The bolt is missing to mount to dash panel. Could be from a mechanic.

RH A/C vent.. The screws are supposed to black, the bottom two weren't. One of the clip retainers broken. Not too many reasons to take these off. Edit, found a chuck key inside the duct for the RH A/C vent.

Center A/C vent.. One of the nuts is missing. Seems these could just come loose. Of all the pieces, this is the only one that was noticeably loose.

Off topic, shame the duct hoses are so wide. Would make for a much cleaner build if more narrow. I wouldn't think they had to be this wide. Any recommendations for replacements? That's not to say I wouldn't use OEM or replacement OE.
