I've found the cf shock tower holes to be very diffficult to screw onto the bulkhead as they are abit tight for the screws so loosened them up abit with a drill, also the 2 screws that attatch the motor support T plate from the bottom of the chassis don't sit flush so again i drilled the 2 holes very slightly so they were abit wider and the slightest bit deeper so the the screws now sit flush
