just spent almost all day with this (should be a 1 hr job). after I got them installed in the bumper cover, went to install on the car, and WHOA! they can not be installed. no space behind them...they hit the bumper. I had heard thru the grapevine that sometimes the bumper needs to be cut to make clearance for fog lights. is this true? anyone else run into this? spoiled my weekend! and how do you cut a 3" thick square chunk of iron tube? thanks in advance for any help!
