The threads will have some carbon build up so you can either use a battery terminal brush and some carb cleaner to clear it out a bit... or carve 3-4 grooves across the beginning of the thread on the bolts to basically turn them into thread chasers... the second option is what I did. you will get them to thread in only a little way, then just work it back and fourth like a tap.. it sill slowly clear out the threads, and work its way right in there.definitly NOT 9/16.... definitly 5/8-11 :coolsmiley:</blockquote>
