They're all the same other than the early small spline cable transmissions ('89 - '91) B16, B17, B18, B20 doesn't matter.

The only other thing I will say is clutch disc sizes can differ between manufacturers. As far as the D-series stuff went the Japanese production models came with FCC clutches. US/Canadian produced models came with Exedy/Daikin clutches. The FCC clutches had a slightly larger disc (same flywheel, same pressure plate diameter) FCC clutches have a very distinctive friction material and the fingers on the pressure plate are quite fine.

FCC OEM B-series disc and pressure plate:




Exedy OEM B-series disc and pressure plate:
