FWIW:
I have a '97 OB w/ stock fogs. And an '03 TS w/ Hella 500 fogs (but they're not amber, they're clear). The Hellas are noticeably better. Wider pattern, sharper cutoff, and brighter.
If one of my fogs went in the OB, I'd get Hellas to replace them. The 500's for the TS were about $70 for the pair. I just used the stock wiring, but mounting in the OB would be different so I can't help much there.
Nice clean OB, sybir! Mine looks a bit more... used, LOL.
