Thanks both of you.
I measured my fog light hole. Unfortunately, the hole seemed to be NO LARGER than 5". I'm not sure. Maybe I measured wrong but that'* what I found. I have a 2001 SSEi so maybe somebody else might know. Those lamps seem to be just a little bit too big (I'm not sure where I should start looking on the diagram because I don't know which parts need to be able to fit) and I don't want to spend $1,000 and then have them end up being a little bit too big. The 610'* come in 4" but those are just a little bit too small for my taste. Does anyone know if those lamps that toastedoats posted will fit in my hole?
