I've attached a picture which illustrates the problem. Every other screw on the chassis/bulkhead/wings is done up and the chassis is flat. Both belts are off and the diffs are out/dampers off. As has been said before the countersunk design of all parts means you can't build tweak in or out of the car.

Can anyone compare lengths with me? Particulary I'm intersted if a new top deck might sort it if I have a duff one.
