Oval fogs layed on their side would look best, something like the '03-'04 cobras.. The round lights, like the gt bumper lights, look ok on a gen 2, but, on a gen one with short wide lights, round fogs would look way out of place I bet.
I think the '03-'04 style would look great.
I think the easiest way and best way, is to build canisters, cut holes in the cover to match, then 'glass the canisters in with some thin aluminum bent into shape in 3-4 places around each hole to limit flex between the two. Prep, paint, wire, voila.
