Would love to see more up close on the air ram to radiator... looks robustly made and not very obtrusive to appearance.
And in the spirit of Warren's favorite site, BAT, I shall now poke fun at your perfectly outstanding vehicle.
IF it were me, the short arch does bug me. I can see the pass side is at least 2" longer than the driver's . And I appear to see the front bumper is also slightly twisted, with the driver's side wing pointing down ever so slightly. This make the gap appear slightly larger on that side as well. IF it were me... I might cut the pass side to match driver's side length. Then, I'd take that 2-4" of cut material and have it approximated with like material to original arch length. Then, depending upon weld tack capability, I'd consider tacking it to the original pieces. But, as a fall back, I would mount the new longer pieces to mate closely to the original arch and perhaps even (agast!) tape or glue together from the back side to minimize any small gap there. Best of both worlds. Cost would be no issue, of course, because the arch strip alone is worth as much as say, all of DD's car in current state.
Lovely car!
