Taj,
Are you talking about the red anodized braces? If you have the red anodized braces, then unfortunately they are not a direct bolt on to the truggy. You can still attach them to the chassis though.
Here are two ways I have done it.
1) First dremel off the raised edge on the bottom of the brace next to the where the screw threads in from the bottom of the chassis.
2) Notch the chassis for the raised edge and drill a hole through the chassis for the screw and one for the raised edge. This is the harder method, but it feels more solid to me.
Otherwise, if it is another brace, I might need to see a pic to be able to help you out.
