"SS Hardware" hardware being the operative word. The type of SS bolt you would buy at a hardware store. Unknown quality=unknown result except perhaps "itelkillya". I am not a great fan of Gr9 bolts unless what it is in is rigid. They have been known (as well as gr8) to "pop" the heads off. If you analyse the loads imposed, in these types of cars, a good quality Gr5 will more than likely do the job.
