I recently acquired some zj louvers but they didn't come with the drip pans. The bottom of the louvers have these little steel bushings (they aren't real bushings but they resemble them) somehow used to mount to the drip pans to sandwich the hood. Has anyone installed these without the drip pan and if so what approach did you take? I am sure I can figure something reasonable out but I wanted to ask the forum for ideas first. Any help is appreciated!
