Can't help you with specific parts, but in shifter terms, what fits 02A fits 02C
The differentials are different, the right side axles are different and the shift towers on the transmissions are different. The internal selectors are the same in the transmissions and I would assume (but don't know for sure) that the box in the car is same.
TMTuning.com sells a short shifter kit for a B3/35i but I don't know if it will adapt to a 02C transmission.
