pic 1-2) it works out perfectly that the outer holes of the b3 tower line right up with the top center hole of a standard rc10 front tower. simply screw them together. now with that done, the standard tower becomes your drill, cut, and grind template. so, use one that you don't care about.

pic 3) since the b3 tower is narrower than the standard tower, the one camber rod hole that you can use from the standard tower is the inner one. so, drill those 2 holes, and the 2 holes for the arm mounts. then cut the excess of the b3 tower off of the bottom, and grind away the little bit around the curved part of the standard tower. take the 2 towers back apart, and you'll be able to dress up the bottom of the b3 tower. mainly to kinda square it up and make some nicer edges. it'll look something like this.
pic 4-5) now, simply put it on the car. easy mod, and it looks pretty sweet. especially the woven graphite tower on a woven graphite chassis.
