I have just fitted a pro staff reduction gearset to our 2012 jimny with 64,000km, and have no use for the old gears.
I believe the manual VVT models are 1:1 so if you've fitted enormous tyres or don't hit the highway much these will go on with an auto chain, for a 32% reduction.
Not sure what they're worth as the chains are expensive and it's a much bigger reduction than most people want.
Located Brisbane Southside but happy to post.
