not 100% mate, but the MA,s have a 5 bolt pattern on the crank flange (CG,s 6 bolt) and the biggest MA clutch (bar ST) is 160mm
so you could fit a hybrid clutch like mine, and a preface 1.0 k11 g/box like mine
I will swap you my manual superturbo 5 speed for your auto, cost a little in postage between UK and Australia but defs be cheaper than buying another box, I will send clutch as well as long as you send me all the bits for the auto,
