Current price for a rebuilt rack with a bronze passenger-side bushing averages around $300 from the major Pantera vendors. Given the importance of being able to steer straight and likelihood of having to tear down any 'E-Bay treasures'to see what's actually there, I'd suggest you look at your favorite vendor's site. Most have a trade-in core policy, and the rack R & R's with only hand tools.
