Hmm ok, good thoughts. It's not magnetic. I licked it and did not receive any pleasure so it's not chocolate.
I did upgrade from the solid posts to the springs for the clamshell latch, and the hole fits the old thread size perfectly. There's even black paint that looks correct for that area. But, I don't think I dropped anything, and there's not another one in my spare parts?
I do have the Ford pulley, installed by the previous owner. It's definitely not the two on the top in the pic, but it sure looks close to the bottom two. But just what pulley is it? I assumed it was the pulley on the supercharger itself. But all the pulleys I can inspect on the SC belt only have a single center bolt. I can feel another one below the SC that has four bolts but I think that is something on the other belt?
I'm getting ready to do the Mojave Mile, so if this is something significant I need to figure it out, before the car does at 190.....
