On a 79 truck with factory roll bar, ie Macho Power Wagon, what hardware was used to mount the roll bar. The guy that did my truck used self tapping screws!! I’m thinking of going with 1/4” stainless bolts or should they be body/roll bar colour or black?

 

Color is whatever you want. The bar just mounts in the bed, doesn't it? I would be tempted to get some plates cut, and holes drilled and tapped, to run the bolts into.....
