Is the 2600 the kind thats almost the same size as the stock ones but has a black bracket? Ive got some pilots on mine but i cant recall what series they are. if yours are what i think they are then they are similar in geometry as mine are and if thats the case then i just used the bracket and put it into the bumper portion above the fog light hole that way they are flush with the bumper instead of being recessed and look better in my opinion but you may have something totally different so this may all be useless to you.
Also on the sig thing ive had to go down and put a check in the sho ur sig box on every post or otherwise it doesnt show up. Im assuming to save bandwidth or something.
