Did Chevy use actual stencils back then or was the tape applied free hand using some guide stencil. I ask this because even though the assembly manual lists stencil, why would they show gap measurements between the thin and wide lines if a stencil was used. In my mind I would think one stencil would have the 3 stripes in a common base for lay, press, peel back and spray so all the dimensions would be automatically in place. I understand having starting edge references though.
Anyhow...I was able to reach up top of the lift and take a closeups of the stripe end on the 67 4B LOS and as you can see it ends at the bumper top with the bottom edge following the fender curve so the front rise showing upwards gives the illusion the bumper is curved downwards (notice the edge bleeding under the front thin stripe...so much for mass production). Excuse the dry and crazed original paint....the old girl is showing her age. As much as am hesitant I may document every inch and then just restore.
