You need the Integra shift bushings. The rear bushing is the same, the front bushing is completely different. If your using a B-series tranny, you need B-series linkage and B-series bushings.

I believe the shifters are interchangeable. I know people use their stock Civic shifter with Integra linkage during a swap, so I'd imagine it's the same for aftermarket shifters (never tried it though). Seeya.
