If you could get the ratios out that would be handy I'd like to confirm what I thought they are. Would also be interested to know if the diff is a common to any other models and any specs there might be on that. ( num teeth, dimension, pitch etc.)
Interesting that the AGP runs the m32 and not the c635 family box as the AGP box sounded as rubbish as my Evo but the M32 in the Alfa was quiet, must be a soundproofing thing.
