Looking sweet and looks like we'll both be coming in for a landing right about the same time. I love that even your headlight buckets are correct. That is dedication.
I think your "spot-on" French Blue and my "Let's just use a common Toyota color" Voodoo Blue (aka Rustoleum Sail Blue) are pretty similar, and pretty close to "correct," but I don't concede yours is righter: I mean, a lot can happen to a pigment in 63 years, and as any restorer of fine paintings will tell you, often the "right" color as seen in period is much brighter than what's on view today in a pristine, unrestored work of priceless art. ...
So it's probably best for you and I to drive our respective Spyders to Stanistan next spring and meet there with the new owner of Seinfeld's old car and a couple of PCA-certified concourse judges to hash this out.
I'd be up for anything but a drag race . . . with that engine you're installing, your license plate could be "BLUBYU".
