Why not just buy a Cadillac emblem and replace the Bow-Tie with it. Or get a caddy grill and hack it up till' it fits in place of the Chevy grill. The whole clip seems impossible on a budget and very labor intensive. I like my truck the way it is.
"Bought a Chevy Truck cause I wanted a Chevy Truck, if and when I want a Cadillac, I'll buy a Cadillac." And that ain't from no song...... nuff said
