I have a 68 Barracuda Formula S fastback, its a street/strip deal and I am not interested in originality but I am working on making the interior "niceish". The car does not have a headliner, I do have the bows and I actually have a new headliner that has never been installed(for 20 years). The car has a full roll cage but that doesn't seem like the problem as much as properly installing a headliner. My understanding is that the factory headliners are tucked under the windshield and back window, there is evidence on my car that supports that as well.

What are my options to get a headliner in my car, I am not against going away from the bow type either but I need something on the ceiling, tired of getting baked in the summer time. I really don't have any interest in getting the glass pulled just to install a headliner. TIA
