My passenger side sail panel fell off and i dont no where it is any advise would help

 

First you need to find a new one, I think it is the same part on all (vert & non-vert) TAs and Camaros, but I could be wrong. I glued mine back on with plastic epoxy, it is now stuck on much better than it was from the factory. The other option is to buy a new one from the dealer ($60 I believe) which comes with the factory double sided tape.

 

Those panels screw on with two small screws. I bet yours just backed out and it fell off. On any top I do I always screw and glue them on.
