The options are....
rebuild the standard box with shotpeened gears etc
rebuild the standard box with a OS Giken kit
buy a Z32 kit from Mazworx from the states
or...
do the kit myself

I picked up the box from a memebr of the 300zx OC and have been playing with it for a few months now on and off. I am lucky that I have a spare SR20 and S14 gearbox in the shed to work with.
If anyone is interested you can have a look over here on the SXOC....
