youre talking about the circle ones that take 880-series bulbs? they will stick out from the bumper because the radiator support thingys on the sides are in the wrong spot.
from what ive found, the blazers have a depth (from tip of lens to end of the bulb) of 13 cm/5.1", BUT the bumper only has space for a ~5.5" light...ish.
but wtf ever, do it anyway i guess.
as a side note, i think i found a bomb setup for projector fogs. i need a depth spec and then i might *might* move along with it. looking like ~$150 though, and thats with halogen bulbs...i wouldnt get HID until i get the retro done anyway
yeah, i think these are the ones ur talking about, the power wire for both fogs are really short, so i will prolly putting these on each side of the liciense plate. and damn 150 for a pair of fogs w/o HID, some expensive lights!
