Albins Gear 1st to 5th dog engagement gearbox, GroupN Ratios, 4.44 final drive. Sti 1.5way front diff, stock 4kg centre. Helical cut so pretty quiet while driving. Strong gearbox, I bought it last year and it was virtually new when i got it, has Albins shift rail interlock kit and is full of delcious fresh oil. I believe the gearset itself is worth
$7-8k+ and the front diff is worth
~$2k plus a gearbox and assembly etc. Ideally I'd be looking at about $5.5k for the gearbox. Also have an ORC Twin plate clutch for sale eperately or with the box, or i might keep it. Aftermarket 5 speed or 6 speed considered as swap
