I still can’t get to the bottom of numbers. MMC don’t respond to my emails. Personally I don’t think chassis failure is a foregone conclusion. Just much more likely than the better managed fabrication of the later version. A big part of it design wise may well be the triangular brace that was retro fitted. The bolt in is very sturdy between the rails but the centre clamp is fairly weak in its design. Mind was not that tight and I may well weld it in place as I don’t trust it to do its job.
I have to say I do like that internal sleeving method shown above.
