I'm trying to source missing engine bolts.

I bought a 5.3, partially disassembled. Head bolts are an easy get, but long bolts for the rear oil pan or the intake manifold are not something that seem to be found at Rock Auto. Dealer pricing here seems outrageous. I don't want to mess with hardware store off the shelf quality.

Is there an online sales center for this stuff?

 

You can always call your local GM dealer. Do you need car intake manifold bolts or are you using a truck intake?

 

ARP Makes bolts as well. Much better than OEM.
