mate I wouldnt bother looking for bolts from anyone, just go to any bolt / fasteners mob and ask for M12 x 100 bolt with fine thread (1.25 or 1.5mm thread, can't remember) high tensile grade 8.8 or just take your bolts there and they will get some new ones. I go to West Coast Fasteners in Balcatta and probably for four M12 x 100 high tensile bolts you are looking at five bucks.
