Need some junk plastic for repairs

Steve
I repair grilles and plastic parts all the time and tried the shaved plastic/acetone and it works but is also very brittle after the stuff fully dries.
Go to the hardware store and buy a product made by Devcon called plasti welder,its a small two part syringe that you mix up the two parts and apply.
Best stuff I have found so far and its about $6

Just to give you an idea of how well it works
in the first pic all those 72-74 cuda grilles were broken in half and missing pieces including the blue one which is the grille hanging on my wall at the bottom in primer in the 2nd pic
