Okay, so I bought a pair of BBK LT headers and O/R X off a guy. It did not come with the header bolts, collector studs, washers, lock washers, and nuts. What size are these? Are there any stores I can get these items at? I'm doing the install tomorrow (hopefully) as long as I have all the parts. I already have the o2 extensions and gaskets. Am I missing anything else?
