my car has the factory original under-trunklid jacking and positraction labels; I think these are 'protected' from sunlight/rain/etc by being where they are.
The Tire Pressure decal was affixed to the back of the drivers door for 69, and mine was 'missing' when I bought the car in 1976, so I can't comment on that (although I'd love to see some photos of factory original '69 tire pressure decals! (note my car is a mid Sept '69 production so it does still have the VIN decal on the rear edge of the drivers door, so I don't know why the tire pressure decal was missing, but the door decals were not as 'protected' as the decals under the trunk lid.
