    Hi Folks, quick question for the honda tech's here.

    I have a Y1 gearbox (Cable) with Helical LSD (16 Bolt) mated to a B18C and bought a 4.9 Final Drive to fit when getting the box reconditioned. It doesn't fit (12 bolt). That's OK, sent the FD back as it was sold to me pending it working with my setup.

    I've located a Y21 Gearbox with Spoon LSD and 4.9 FD and Hasport Cable -> Hydrualic conversion kit. My question is what else do I need to make that box work with my setup? Will I need to get the clutch/flywheel/PP also? Will the existing driveshafts fit or will I need the ones from the Y21?

    Any input greatly appreciated!

    I believe the clutch/flywheel/PP will work from Y1 to Y21. The existing axels will work, am assuming your using 90-93 DA axels. As far as cable to hydro, I have heard that you need to mess around with the clutch pedal assembly.
