I did a search at the auto parts stores, napa, AZ, Advance, none of them had the right one luckily i found the spare.
It is the bolt that goes from the caliper bracket to knuckle and it was the top bolt which is worse. I just traveled 100 miles on the NY Thru way, went to the exit and slowed down, by the time I hit the toll plaza it felt like i was going over rumble strips. I then left the toll plaza and it was vibrating like crazy and started to lock up. I got out and checked and saw the top of the brake caliper leaning against the aftermarket rim. It scratched and etched a ring around the inside of the rim like a record groove.
I took the wheel off, Swapped the lower bolt and put it in the top hole and tightened it good and made it the rest of the way home about 15 miles.
Being an SHO owner, I always have a huge bag of pretty much all the tools I need to do most jobs on this thing lol.
