Talk to Richard at WCCH he has hooked me up with ALL my ARP stuff, he has the best prices on them hands down not to mention he is an awesome guy to deal with. I checked for the PN but I dont have the ticket in my garage. He may still have a copy of my ticket at his shop. If all else fails I have a gm hightech aritcle with the PN in it somewhere.

 

I got a box of them on my lap right now.. ARP Part # is 234-5608-SB ARP description says "LS1 & LS2 side bolts only" These are the 12 point ones, Im sure they make hex bolts too but I dont have that PN.
