A couple of questions about the 99-06's

This is good to know.

I do not prefer the "cat eye" front end; if something ever happens I will probably switch over to a GMC.

I assume the same is true for putting an '02 Chevy front end on a '03 and later Chevy?

I did not like my cat eye front end either, and the bumper and fenders were rotted so I put on a GMC front clip I had. I also went above and beyond to put a Denali bumper on my 2500HD, which meant cutting the frame and welding on 1500 brackets.

The core support is taller by about 2" due to the frame differences, but the fenders line up fine. You also have to change the plastic headlight brackets but thats easy. The cat eye ones are specific to that front, the GMC and 99-02 are all the same according to the part numbers. The fender inner liners are HD specific as well, but are the same between all years as far as I can tell. I reused my HD liners on the GMC fenders. Flares are all the same too.

GM did make a 1500 Denali, but not a 2500. It was worth the effort as I like the Denali the best.

Were you able to get all the panel gaps set properly? That would be one of my main concerns.

[MalibuSSwagon]

Yes everything will line up just fine.

Are you guys sure that the GMC’s front radiator supports are all the same? I have a 2005 GMC 2500 that I put a 2006 Chevy HD fenders and hood and I can’t figure out how to get the hood to fit for the life of me. My GMC front end was aligned perfectly... What do you guys think?

I used the same core support to put the GMC front end on my 03 Silverado. You likely just have to adjust the panels once you unbolt stuff the alignment changes.

Ok. That’s the one thing I haven’t done. I figured since the gmc front clip was perfect aligned that I probably should leave the front core support where it was. I’m just going to loosen the entire front...
