71 Demon one piece headliner question

No, my 71 race car has nothing up there but what foam insulation still remains and some shards of cloth. That is why I was asking about putting in a hard headliner. I already have a hard set of sail panels I bought from a member here. Haven't even opened the box yet. I am not sure how well the install of the hard liner would go. There are bars in the car and the thing would have to be slid through the windshield opening over the bars to get it installed. May not be wide enough.

It should fit just fine. The roof structure didn't change any from '70 to '76, and the Demon is the same as the Duster.

The roll cage will complicate things, but the ABS 1 piece headliner is pretty flexible, I think you could make it work a lot easier than the cloth type. In fact, the ABS headliner comes shipped rolled up, it has to be unrolled and laid flat prior to installation. I don't think it would be that hard at all to sneak it past a roll bar.
