Can anyone tell me if these are flexible or not?? How thick are they? The reason I ask is, I have a rollcage in the car and the main hoop is real close to the roof. I was wondering if the headliner would flatten out enough to be able to get it in between them.

 

It should pm NickyG about it... thats my pops he just installed one for t-tops like 2 weeks ago

 

It's plastic... about as flexible as the interior body panels in the car. It'll move, but it will crack as it gets old

 

I just bought one of these, and yes it is pretty flexible. It should work for you.
