A close up pic of the braces and the rear battery hold down. That little piece bolted to the chassis in the battery bay can be moved forward or backwards to allow for battery placement. There is also one in the front.

The chassis has little cut outs to run wires through. You can also see the battery stop.

OK, here is another problem I ran into. When you install the rear bumper you can not align the two screws on top that go into the tranny holding the motor guard on. One of the screws on the left side of the upper bumper hits the motor plate causing the miss alignment. The way I fixed it was I dremeled a little off the bumper (about 1/8 of an inch). This allowed me to put the screw in just a bit further clearing the motor plate. In the next pic you can see the top screws are in now and the bumper does not hit the motor plate.

The nerf bar parts. I had to look at these for a few minutes to understand how they went on.
