Just sent in for my July 68z. Definitely fun hitting that paypal button, wish it could be here in my Easter basket but I know that is too soon.
I do wonder if having the protecto-plate in hand before you get your results helps convince some that your protecto plate is not a fake. I can see fake protecto plates being made after getting these docs as you really don't know for sure where your car came from, unless you had a small shred of some paperwork on the car.
