Duster grille resto.

I just fixed my grill. I used plastic weld and it worked well and was easy, it is a two part product. The mini saws sound cool, but you might have success with a couple of pliers and snapping the broken piece off and the filing it to shape. I'm very budget minded and I shapped everything I did with various files. I cut my repair pieces with side cuts and filed to final shape. The plastic weld sanded easily. Post pics of your project!
