Dash knobs

Hey all, i'm going for a custom look for my Duster interior. I already have dash panel and gauges, but i want to get some nice polished knobs for headlights and wipers. I came across these http://www.billetspecialties.com/item.asp?cid=8&scid=195&pid=275&rdir=1 but am not sure if they'll work. Does anyone know or maybe know of somewhere else i can find knobs?

Thanks,
RS
