Intake (heat shield) and metal gaskets?

where can i buy those rivets ?
does anyone have a vendor and a part number?
thanks...rich
Apparently you can reuse them. It seems like they can be driven back in with a good blow from a hammer. Maybe use a little JB weld but that'd be a permanent thing might not be able to remove them again. Or maybe just a little thread locker the orange, it's removable.
Unless you lost yours or they were destroyed while removing. Possibly a fastener company might have them?
