I had thought his car had black trim around the canopy glass, not chrome as the car in Ziebart's commercials has. Perhaps Enslin has made changes to it. Overall, it's a sharp-looking copy, but if only a few details were cleaned up. The speedometer is a standard 70s 'sweep' guage. The steering wheel is an aftermarket piece.
Nice touches are that steering wheel and the gas cap above the interestingly-detailed afterburner.
He suggested it might be a hood-tach, but I see no hint of a guage face. I'm betting it's there for clearance of the master brake cylinder, which many cars, with power brakes, have mounted at an extreme upward angle. One obvious error is the lack of front turn signals that should be set in the grille at each side. For all I know, these are the same two cars noted above.
