Nissan are useless. Went from quotes between two places from $255 and $280 they would match it at the other place however.
Rockdale Nissan would not supply a product code and was anoying the shit out of me, however with a VIN Artarmon will match it, Thank god!
Anyway thanks to all who helped, Bearings aftermarket dont exist for the R34!
Cheers
