68 firebird front bumper help

[benloibl]

Hi I am a long time lurker on lateral-g and wanted to see if someone could help me out with a couple of questions. I have noticed in a couple of rendering by cars by kris and a couple actual pictures of some finished cars that they are somehow narrowing or modifying the bumper of the 67-68 firebird. I would appreciate it if someone could explain to me how they are doing that or if they could provide a link or even the name of a company that I could contact regarding that.

thanks in advance
