And those crayon markings? That "X" on the door is so the door guts installer knows which door to throw his lunch bag and crumpled Coke can into.

Reminds me of our old 1972 Satellite Suburban 9 passenger wagon (Rallye Red with black interior!) We always wondered why the tailgate rattled so much and how the rear window washing mechanism never worked. My dad finally brought it into the dealer and the dealer pulled out all the assembly-line parts, rubber banded together, and clanking around in the bottom of the tailgate. I never thought to ask if the "X" was there, though.
