Well it's been a few weeks since I had an update, so here we go!!
I decided to pull the trigger on a GM Heritage grill, because I got tired of looking at my big gold bowtie and "not so aggressive" (IMO) front end.
I tried to install it on tuesday this week, but I did not have the right extension to reach one of the bolts on the bumper to get it off. I was also mistaken on which bolt to remove, and that was cleared up by some overly helpful C5.com members here! (I love these forums).
So I installed the grill with the help of a co-worker wednesday and this is the result :
