Big Bear Choppers exhaust

[NL01]

I have a BBC Sled Chopper kit that comes with the SuperTrapp radius (2 in 1) exhaust. I don't have EFI, so I need to plug the two holes which I assume are for the EFI sensors.
Is there a recommended way to plug the holes or can I just get 2 M18 stainless steel bolts at the Home Depot and use those?

You could. We do offer a kit, P/N 100-7175.
