I was on GM parts house and can't find the main bolt. Anybody know the part number for these?

The search tool on this board is an amazing invention. You didn't specify for which engine, so I'm assuming it's for the '00 Trans Am.

I tried a search and all I came up with was part numbers for ARP. This is for a 98 Z28 and looking for the stock GM bolts. I assume they are all the same?

I hear you, it's hard to sift through through all the info on here sometimes. Yes, those part numbers are for 98-02 LS1 engines.
