I noticed that my '89 still has the Formula GPs on it! I need to replace them, as I'm sure they're shot. I don't guess they can be rebuilt or anything, can they? I figured I'd hang onto them, in any case. David Reynolds Southern IL '87 CSX #321, '89 CSX #321, '04 SRT4, '82 Rampage (project or parts car?), '98 Grand Voyager
