your opinions on this sharktooth grill

If all that is wrong with a sharktooth grille is a few cracks, it should not be too difficult to fix. You will have to re-paint the grille after the cracks are repaired.

I had a problem with the Demon grille that had a small chunk out of the middle of it. Found another grille that was in awful shape, but had the chunk that mine was missing. All it took was some surgery with a Dremel tool with a cut-off wheel. I cut the rough edges off the spot where the chunk was missing, then cut out the same piece (only a little larger) out of the disaster grille. File and sand until the part fits properly and finish off with a little bit of body putty. Let thoroughly dry, then re-finish. It's a little bit of a Frankenstein approach to getting a good grille, but it worked for me.
