What should I do for a rollbar?

[clxfiles]

I have chopped off the top of my Mustang Concept for my SE and I want to put a rollbar. I left some cuts on the body to maybe put a plastic piece across the top and make it look like a rollbar or I also sliced up an unused spoiler that I can try to glue to the body. THis is my first attempt at a body mod so would like any input from the experienced ones out there.
