I haven't made a template for sheet metal glovebox, but have an original cardboard one that could be used. I think it'd be easy enough to cut the sheet metal, but making the opening correct for attachment to the dash might be a challenge. The cardboard ones can flex a bit when installing. I'm not thinking there would be enough demand for a sheet metal box. I realize it would be more secure than the cardboard one, but who's going to steal your registration and insurance from your truck? I still believe people are basically honest and wouldn't do that.
