The standard vent extension has a lip on the drivers side that slips into the opening and then retained by a single screw on the passenger side.

I've had good luck with AMK. I don't know if they are always right, but they are very detailed on application and I bought from them a few times when I knew the fasteners weren't even close to original or I was missing parts completely.

They show something with flat washers in their 68 master body kit. It is labeled for the front bumper "stabilizer brackets". I'm not familiar with your assembly, so have no clue if these are correct but you may want to look if you haven't:

Here are the bolts and washers that look similar to OG68's:
