Here are the photos of the real deal (1991) I added some dimensions into the photos. Hopefully that helps a bit. I really don't know how important it is to have this truly exact. One question on my mind about the chassis setup and the composite tunnel has to do with the trans running up the center tunnel. Would that add to the rigidity of the chassis and without that large transmission running up the tunnel could there be strength problems? The side rail that overhangs is 6mm x 2 mm which may be the reason it lines up better on the inside but it does over hang the outside for the purpose of holding the door jam.

The second thing that I do know for fact from working on many Diablos is that every diablo I have ever been under has twisted just behind the firewall at the lowest beam. This is very noticeable if you get underneath the vehicle. It doesn't seem to affect the performance of the vehicle but I have actually been under a couple diablos' that have what apears to be rips in the lower tubing from the twisting of the vehicle behind the firewall. They all had similar damage. They ususall rip where the firewall meets the lower tubing. That is where I have noticed the tears. From the factory that chassis is flat and straight across the bottom but give it a year on the road with a lead foot and the chassis will not be straight and flat.
