Same location. Mine is a June built car so maybe it was number 77 for June?
Don't believe so IMHO just the rotation number for that car - so it was situated between car 676 and car 678 on the final line
Unfortunately I have no build sheet and have found no other markings. Going to power wash it once more then blast it soon. I will go slow and easy and keep a camera close by.
Not as familiar with Dearborn rotation numbers. Check places like back of original door panels, heaters, radios, seats and other parts of the car - just be alert
