Henrietta, You see the pan with the half circle cutout? Put that one on the passenger side!
I like that idea. But I think I'd do both - tap the holes to make installation easier, and then put nuts on the protruding end of the bolts. Belt & suspenders, yep, but would also keep the bolts from working out due to vibration.
You can see the gloss black engine pan on my tudor here. This is POR 15 over clean tight rust. It flowed out and looked almost like porcelian. Gas just sheds right off incase of a gas leak.
