Bob's is a salvage yard -- the biggest in tin -- and they have a pretty sizable shop with new stuff (and some uses stuff -- they've been combing swap meets for chopper/bobber parts too, peanut tanks, fishtail exhaust, lights, etc.). Their tires are all upstairs. I would buy tanks there for seat bumps as well; if the front end is dinged up but the rear is straight, they'd sell 'em to me for as little as $5 (I've been going there for 15 years, though). It's not the Harley Bob's on university. They're on Elwood, in between 7th and 16th streets, just north of Broadway.
