New Shift knobs to fit Trans Am 6-speed Thread???

Does anyone around here know of any good websites that carry the shift knobs that fit the TAs thread?? I know that some shift knobs have to be custom made to fit cars such as Firebird, camaro, corvette. The reason is they say is b\c they have a special thread unlike most cars have which makes it really hard to find a new shift knob for it. I recently ordered a "universal fit" Ichaban shift knob and when i got it, the hole was too small. I guess universal shift knobs don't include the muscle cars. So if any of you people know of any websites where i could find shift knobs that fit a 99 trans am 6-speed, i'd like to know. Thnx
