For sale section will be opened again today and i'll be taking care of it. Admins higher up are making the national sale section as one and we'll have our own sub group apparently.
But until then it'll remain open.
As for no events etc, why don't you organise one Char.
Looks like a OS Giken unit. Being the front diff i'd like to say its a 1 way. But ring/email Otomoto as they are an OS dealer and they will be able to tell you. Looks to be a clutch type LSD from the pics you've put up??
Jack it up and have a good look, even wobble the wheel to check the wheel bearing. Put it on axle stands and get someone to "drive" it while you listen out for noises back there
I am doing these on my 32 aswell at the moment. But instead of getting them through amayama, i went down to the local bearing store and matched everything up. Set me back $50 each side approx. You don't need to replace the dust cap though unless you damage it when pulling it apart.
Will post up part numbers when i finish work tonight
