Knurled Dash Knob SO001-50400Knurled Dash Knob SO001 50400 001 50400 Add some shine to the interior of your hot rod, custom, truck, VW or whatever with these SO CAL dash knobs. Machined from aluminium and highly polished, they are easily installed and held in place with a set screw. Heck we've even used them, especially the Art Deco and Forty knobs, as draw knobs on our cupboards and kitchen units. The Art Deco and Forty knobs are particularly great for period restorations.
