Sorry for the wall of text but I have lots of questions and, so far, have found very few answers. I have a 2003 Yukon XL 2500 and want to "beef up" the front fascia a bit so I'm curious as to what my options are for front bumper swaps with as little permanent frame modification as possible (preferably none). Are my factory bumper mounts the same as a 99-02 Yukon since the bumper is visually the same beyond the 03 GMT facelift? Or does the 03+ Yukon bumper bolt up differently even though it looks the same? Are the bumper mounts different on a 2500 vs a 1500 even though the two are visually identical on the SUVs? I know the bumper mounts changed in 03 on the 1500 trucks but I'm not sure about what, if anything, was changed on the 2500 SUVs between 02 and 03. Which of these bumpers would bolt up to my 03 2500 without (or minimal) cutting and welding on the frame: 99-02 Sierra HD, 03-06 Sierra 1500, 01-02 Silverado 2500, 00-02 and/or 03-06 Suburban/Tahoe? I ask about the Silverado/Suburban bumper because I'm open to the idea of "converting" the whole thing into a Chevrolet but I need to know what my options are. Any help would be greatly appreciated.
