Hello, I know this is a Tahoe forum, but I thought there would be more knowledge on this forum than the truck forums. I have a 2004 Silverado and I want to convert the front end to a 1999-02 front end. I got the truck for free or I would just buy a 99-02. I just want the challenge of customizing my truck. It seems to me if you can convert a 99-02 to an 03-06 then it could be done. I just want to make sure before I go spend a lot of money only to find it won't work. Thanks for all your knowledge!
