Very nice carryall! I think it looks very stylish. To bad the windshield in those years wasn't stationery. These Visors are getting harder to find. It took me quite a long time to find the right one to fit my 51 Chevy pickup.
Wonder if a person did a mockup using masonite material to do some research and development. Maybe it would be just a matter of adding lenghth to some of the fastener points. Would be real nice to make it work. Whatever the outcome, Good luck.
