check partscheap.com. I did the same swap in my Premium. Its about $85 for knob and boot to match. Looks so much better and has a great feel over the cheap one that Ford put in. At first I really wanted the 401A aluminum knob, but I read how its cold in the winter and hot in the summer, plus its expensive. I didn't know there was a Boss parking brake cover....have to look into that.
