Does anyone know what this type of clip is called and where I can find them? I'm missing one of these clips from the Targa top support in the back hatch area and need to find a replacement.

Those are called "J-Nuts"

OP - Yours is actually a M4.2x1.41 u-nut or j-nut. Should be a very easy find most everywhere. M4.2 is generally thought to be a #8 equivalent I believe. J-nut is a bit different than your snapshot. Your snapshot is a u-nut.

Fastenal would likely have a correct style to match and probably singles. 13217 or 13225 Auveco would be possibilities and likely more.

If you've a very old GM dealer in the area. 1635216 or 12338121 might be on his shelf.

Just another option. only 6 bucks if you have a harbor freight nearby.

I've gotten them before at O'Reillys Auto Parts. Small packs with multiples, Dorman brand IIRC.
