Regarding the Quantum TD transmission and flipping the differential over:
What offset are you referring to, Andrew, when you mention the offset's not being the same? Is it the shims, S1 and S2, that determine where the differential sits in the housing? Or an actual left-right positioning that isn't the same?
If it's just shims.... well, shims can be adjusted! If it's the actual positioning and it can't be shimmed, well, we're back to the drawing board!
