Left hand drive chassis

[alga]

There were plans of LHD chassis here before the forum hack.
I'm nearing the stage where I have to make, or at least plan, the tranny tunnel. As far as I remember, the LHD chassis wasn't a simple mirror image of the book one, right? Also, I remember someone complaining that on the suggested LHD chassis the clutch cable attachment on the Type 9 bellhousing is fouling the tranny tunnel.

What should be the centre offsets of the U7 and U8 tubes? My plan is to put the driver side upright so that the MT-75 pedal box would fit, and leave the passenger side upright at 214 mm from centre axis, so that it sits square with BR9 rail. Makes sence? But what is the width of the MT-75 pedal box?
