I DON"T believe the bumper gaurds were further apart on '69 as a earlier post said. If you look here the guards are on the outside but notice in the older pic someone added those TALL guards in the middle and moved the factory guards out!! That is very odd looking with guards on the out side! Maybe this is where the poster saw this without seeing the old pic? I have car #29 survivor with 21K miles and it is correct position as factory.
