Thanks for the compliments. The car is pretty solid but did get tagged in the LH rear very early on when it was still LeMans blue. I've got that all fixed now.
The remnant of the decal is a reproduction Z28 tire pressure sticker so that's no help. I feel the factory applied white paint on top of the cowl on a LeMans blue car (U-U paint as shown on the cowl tag) is stronger evidence anyway.
