The front bulkheads are secured to the chassis with six screws. 4 M4 button head screws and two M3 that go through the front shock tower and chassis and screw into the front bulkheads. The rear ERBE bulkheads only have 4 screws to secure them to the chassis, two M4 button head screws in the back and two M3 screws that go through the rear shock tower. I wanted to have two more M4 screws to hold the rear bulkheads to the chassis like the front ones.

I drilled those right through with a 3.3 mm drill bit and then made M4X.7 mm threads in the holes.

I drilled matching hole in the chassis with a 4 mm drill bit.

Now I have two more M4 screws that secure the rear bulkheads to the chassis. Since my rear shocks are a bit higher because of the shims I put underneath the rocker posts and rear shock tower, the shocks do not rub on the screw heads.

I will also be trying out a different way of using the M3 screws that go through the rear shock tower and shock caps. I used longer screws that stick out the bottom and I put a lock nut to tighten everything up really tight and secure. A couple hole in the center skid plate to be able to take the screws out if I have to without removing the center skid plate. If you are worried that dirt might get in there because of the two holes, I say, dirt gets in there anyway even with no holes.
