I just realized today that I already have over 4,000 miles on my '69 vert this year. While driving down the road at 70+ I was wondering if anyone has added shoulder belts to their first gen. Of course I would like them to look like they were installed at the factory. I know that the early shoulder belts were clumsey and uncomfortable and not available on convertibles. Retractors are a must. Any ideas? I am sure that somebody else has at least thought of this. Any help or ideas will be appreciated. Thanks!
