Im Modifying my stock grille. I saw another members grille and he did it himself, so Im going to give it a try. I picked up a stock grille on craigslist for 20 bucks. I cut out the vertical cross peices so all you see is the horizontal bars. I plan on getting it chrome plated? and puttuing black mesh behind it. Anyone whos done this, your tips and input would be greatly appreciated. I'll post pics of my progress on the way!

I used a double sided saw, used for crown moulding to cut the bars.

Then I used a deremel tool to sand down what the saw didnt get, then I used a sanding block to sand it smooth. Next I think i might use Bondo to fill in the gaps.
