I am using more cop car roll bar parts to complete the rear frame rails. Using a couple of bends, I will be able to clear the shock mounts and tie into the 1.5 x 1.5 that runs below the upper link mounts. The joint will be mitered.

This will also gime me a "crumple zone" for the rear frame rails. Heaven forbid I take a hit or spin out in it, the 90 degree bends should fold.
