Update:
When I got home today, my motor clamp and pinion were in the mailbox!!!
Then I was down here looking the buggy over and realized that I wasn't happy with the battery tray. I happened to see an old Stampede chassis laying in one of my parts pile, so I grabbled the tools and did some modding to it. This thing is sturdy now.
Also, here are some pics of the body I painted last night.
