How do I install this emblem??

TimsGT, thanks! Year One sent the crappy back plate-style ones with the emblem. I'm not sure the barrel nuts will fit the diameter of the holes, but I'll pick some up and give it a whirl.

69_340_GTS, it's a '72. I haven't found hardly any info at all on this, so that's some good direction. I'm going to do that with the pentastar on the fender anyway. The guy that did the first restoration on my car in the '90s welded over the marker lights and holes for the pentastar. No idea why, but they did a nice job, so I left it as is.
Just make sure you use the good 3M tape, and clean both parts with their cleaner/primer. Guaranteed never to fall off!
