Man that looks good, absolutely nailed the look I want.
Funny thing about the marker lights is, about 6 months ago I put on a set of the "stick on" factory ones, but it was because I had the opportunity to get paint on the car but wasn't looking to customize it and didn't have time for any real body work. Just wanted better than what was on there before I disassembled it.
My preference is the '70-71 flush ones, which I might go for someday. Car needs a bunch of body work so this paint isn't going be the end of the project.
Might look at using the marker lights from a new Challenger, too. They are flush, and smaller than the '70 style, but no idea how easy the would be to retrofit.
Either way, I like the '68 style ones you used, much more classy than the '74 style. And even better that they match now.
