The only decent looking (read: old style) body for the B4 is the "Trinity Killer B", which is not easy to find. The older B3 body is much easier to get. Problem is, the rear body mount on the B3 is a bout an inch taller than the B4.
So, you take a standard OG RC10 front body mount, drill out the bottom hole so that it matches the B4's rear body clip nub, and drill a hole to match the body clip hole on the B4. Then use a body clip or pin, rod, whatever, to hold the RC10 post to the B4 tower. Viola!
The B3 body also takes a LOT of trimming both front and rear to work around the shock towers, even with the +8mm chassis. But once it's done, it looks rather good>
