I plan on using the engine gearbox and ecu from the mx5 running sierra diff and running gear
That leaves me with a few parts to get rid of i have the gearbox that came with the chassis and i bought a diff a few weeks ago which i am collecting on friday all being well
So i dont need 2 diffs and a type 9 diff is 7.5" open diff 3:62 ration bolt on type
Diff £50
Gearbox £150
