I just wanted to throw this out there but I recently just got done making a grill block for my Bravada and I used a GMC Grill since it is directly interchangable and much easier to modify than the Bravada grill. The one that I made it completely weatherproof though since it is made out of plastic and held on with friction and a stragicly placed ziptie. I don't know how yours looks but I have already gotten several complements on mine. I still need to build a block for the tow hook holes though.
Here is a picture of how mine came out.

I don't know if you took any pictures but I would love to see how your truck looked when it was modded.
