We got the kit from US Car Tool

It came with front and rear torque boxes, laser cut sub frame connectors, inner fender braces, core support brace, and a drive shaft loop. I have trial fit everything and all pieces seem to fit nicely. I'm in the middle of installing the inner fender braces right now. I'll try to have Pics up tonight.
XV Motorsports sells similar pieces.
