[SYD] Gen II LSD Turbo Gearbox (E153)

Run into a a couple of issues with my gearbox. Would be easier (and probably cheaper) to replace the whole unit than to pull apart my existing non-LSD box (crunches / broken speedo output drive etc).
 
Not sure what sore of prices they go for, but if anyone knows of one in good condition floating around then hit me up, otherwise I'll have to import one from Japan most likely, cheers.
