VFN Fiberglass I've run their newer OT stuff and have worked with them to create a few hoods for the scene I've done a lot in (late model GM)... Jeannie, 'Mondo, Frank etc.
I have a 56 two piece front end from them and it is very light (box flew out of the pickup on the highway on the way home) and very strong (only one small crack in the corner). It also fit.
I used a pair of thier 55 Chevy doors many years ago and they were really straight and nicely made. They were drag/light weight pieces.
Their stuff FITS thats all i gotta say and the quality is nice also. Never had any issues with anything.
