hmmm i wonder how much 5th gear would cost to buy from them.. that 0.71 ratio seems nice!
There is a .53 that comes from the 5 ganger inlines but I'm not sure if the drive holes are at all similar. Would be nice to fit it to the Q TD. I've not had the oportunity to check this; since I sold my last 5 ganger 8 years ago...
