In my "new" 2013 truck, I noticed holes in the top of the backseat to accomodate headrests. The headrests are missing. Were they optional, or did the previous owner remove them and never put them back in to sell?
So I finally found a seller with beige/tan headrests, these were from a wrecked Armada.
They don't block the view nearly so much when they're down:
Interestingly, one is from the second row, one is from a third-row seat. The Armada had been T-boned and the passenger's side middle row...
