Hi,
Check the sticky on the announcement page- you will need (like me) to follow them & then make adjustments for your MT75.
I think trying to do too much modding elsewhere before making the amendments to the central tunnel, which is a structural assembly, could be quite dangerous.
I don't have the book to hand, but I know the design was completed by an engineer- you may be an expert in car chassis but I am most definately not!!
