convertible styling, roll bar ? rear seat cancel ? Options

[NaderG]

i was wondering if anybody could help me out with theese stuff ... is there a roll bar out there for a celica ? or does it have to be custom made ? how much would it cost ??
note: i am taling about the plastic one , not the metal ones

also , i saw a mustang today with rear seat cancel , it looked nice and i was wondering if it can be done to out celis .. i will try to get some pics of that , but all of you with fiber glass experience : is it possible to buy one for another car and slightly modify it to fit our 6GC Verts ?

Wouldn't the tonneau cover be the leather piece that covers up the exposed part of the top when it is dropped? I think he just wants to take the rear seats out and make a space back there, I've thought about doing this. The way I thought to do it would be to build a box out of wood with doors in it to access places below that would naturally fit into the dips where the seats were. Then for where the back of the seats are I would place either a couple of subs of some more paneling with spaces inside, mesh it all together somehow and cover it with carpeting that matched the rest of the car.
