I managed to find a set of barely used Schroth 4-point harnesses. They are the Rallye 4 models. They tie into the stock mounting points on the front, and use the rear lap belt anchors in the rear. They also have a buckle to detatch the shoulder harness so someone can sit in the back which is nice since they are designed to be installed with the rear lap belts still in place. These are actually DOT approved unlike many other racing harnesses out there. Since the cars will be driven regularly on the street and on the track - these seemed to make the most sense.
Finished tacking in the rear side of the drivers side strut tower. Just need to make some small pieces to clean up the top of the strut tower and it will be time for final welding. Everything fit together and matched the contours much better than expected.
Made a close-out panel at the rear of the pass side strut tower. In order to clear the air dryer for the A/C and to to mate up with the new firewall, it was just easier to make this from scratch. Once this piece is done, the strut tower can be finished as well.
Decided to put everything together once again and check all the clearances one more time before we start welding parts to the car. The hydoboost unit and the hood hinges clear the new strut towers, so we can now proceed with them as in that location.
