The rear diagonal roll bar brace cuts through the trunk and a long diagonal opening needs to be made in the trunk sidewall. Here's a view of the roll bar brace installed. It mounts to a bracket on the rear of the chassis (not shown). As is, this is a moisture problem waiting to happen. The opening for this brace is right behind the rear tire. Once the trunk is carpetted, any road moisture will be thrown into this area and I'll get a wet trunk. I'll add a fiberglass "cover" to this roll bar brace on the outside of the trunk.
