One of the problems that a few designers have faced is how to get around the mounting arms on the MX5 diff, being an ali casting some have been broken through lack of a proper mechanical mount. Some designs have stretched the Roadster design to make the MX5 diff fit but at the cost of poorly designed top wishbones, I don't think there is much wrong with the Roadster rear end so I set about removing the arms from the diff cover. At this point I came to realise that all it does is hold the oil seals in place and give the crown wheel some thing to bathe in. My answer to this was to design a fabricated steel cover that reduces the size of the MX5 diff to that closer to a Sierra unit, and also provides four new mounting holes similar to the standard Sierra Roadster. So you can still use the standard book spec chassis and all you need to move is two tubes (sb4) and two plates cp10 either side of the diff nose and flair the back of the tunnel to clear the drive flange. Obviously you will need some modified wishbones to pick up on the MX5 running gear but they are not difficult to make.
