Installing Fulton Visor on '53 Chevy Truck...

Can anyone tell me how far up the drip rail (measuring the bottom edge of drip rail closest to cowl) should the bottom edge of the dog bone mounts of the visor should measure? What type and size of screws did you use to mount the dog bone mounts? Thanks~

 

Mount the centre clamp first. Then the sides will line up naturaly
