Begin the rollbar install by prefitting the main loop and the side bars to ensure that everything is correct for your chassis. The bar(s) will need to be trimmed slightly, but the parts are generally ready to go. In fact, the end of the side-bar tubes and the crossmember that join to the main loop have already been "fish mouth" radius-cut, thus easing installation. After we trial-fit the rollbar, we removed the carpet, front bench seat and the headliner to gain clearance for the rollbar install. Ripping out the nasty old carpet and headliner was needed anyway because our Chevelle is going to get a new low-buck interior kit in the next few issues. Stay tuned.
