What's the part number to this pulley on the supercharger assembly in the pic (circled in red)? This pulley on the SS/SC I just got this weekend is old looking and I want to replace it before there are any issues with it snapping. Also, does anyone know the part number for the dome light assembly? The switch is broken and I'd like to fix that too!

 

its your belt tens and pulley. just look it up
