It truly is an optical illusion......I went in and measured it again.....7/64".

The space between the double stripes might be about 1/16" to wide at the rivit according to the pics I've seen of a few of these fenders. (The rivit should touch both stripes?)

If you want to see how wide 7/64" is, hold two pennies together.....

In a side note, my frame has been hanging in my garage, by the back door, for a while until I took it down to take pics yesterday. This morning, I opened up the back door to take my dog to the groomer, and low & behold, my 10' step ladder had fallen off the wall it was hanging on and crashed to the ground right where my frame was hanging.......Karma was good to me for once:eek:
