I'm making a list of things to tinker with on the '30 coupe I bought a couple months ago as I won't be driving it again until spring. The windshield will pivot out and open part way, but it hits the gas cap and won't go any further. Is there a simple fix for this, or is it quite involved? It's not the end of the world if it won't open any further, but it's supposed to so I thought I would give it a try. Any suggestions would be appreciated.
