Grille and Headlights
 

Can I take the grille and headlights off of my '99 Jimmy and replace them with the grille and headlights from a blazer without any mods? Or is there some modifications required?

Umm... I'm not sure, but I'm sure it's the same, look at the blazer 1 and yours together, make measure meants to double check

There won't be a problem with the grill. The mounts are the same. As far as the headlights, you'll have to replace the mounting brackets. Then it should be OK. but the radiator frame is the same on the GMC and the chevy. I had to rebuild my front clip from an accident and I used the radiator frame from a blazer. no prob. But also the bumper skin is different. On the gmc it has a dip around the grill. The blazer bumper skin is straight across. So going from a GMC to Blazer grill will leave an extra gap under the grill where it meets the bumper skin.

Thanks for the information. That is what I was figuring but I just wanted to make sure before I got in over my head.

umm.... I don't know if anyone has thought of this but.... doesn't the grill go UP on the left and right side under the headlights? Rather than the bumper going down in the middle.

*EDIT: woops, i was looking at the wrong year. I thought we were talking about a 97 for some reason.
