Solid replacement plastic pegs, 3D Printed. These are known to fit 1985-1990 Firebirds (GM F-Bodies) with the wrap around/aerowing spoiler. Likely fits other GM products of the same vintage as well. Printed in ABS Plastic, and intended to reuse the original metal clips in both the spoiler, and on the rear hatch glass.
Listing is for a package of 6ea. of the pegs, enough to complete one spoiler (3ea. on driver and passenger side). Additional photos show the pegs in comparison to the original GM pegs, the pegs installed in the metal clips on the hatch glass, securing my original rubber Aerowing Spoiler to an 88 GTA, and the style of spoiler that these work with.
Installation is as simple as sliding the pegs into place in the metal housings on the hatch glass, then lining up the matching holes in the spoiler to the pegs and pressing it down. Pegs will slot into place in the original metal housing clips on the spoiler, and the downward-slanted teeth prevent it from popping back off without prying it loose.
