I got started this morning and here is where I am at so far:

I made a small change to the front shock tower. In the original design, you have to screw the body post into one of the adjustment holes for the front shocks. Also, the original design is for the older style truck bodies. So I wanted to make the adjustment so I can run the forward cab style bodies. Some people still like the older style but I do not, lol.

These I the new holes I drilled for the body post. I did not use a straight edge like I should have, so the right side is about 1mm lower then the left side.

Placing the holes here will allow the front end of the truck to be a little higher then the stock position, and when I drill the rear, it will be a lot lower then the stock position. That will give me the ability to use the forward cab design bodies.
