I'm selling my SRR 4.7 final drive. The ring gear on this final drive is designed for the B16/LS sized differential. It will not fit ITR LSDs or GSR open diffs. B16/LS fitment only. 66 teeth on the ring gear, 14 teeth on the counter shaft. If you are not sure what differential you have, I can include a stock B16 diff for an extra $40 bucks (shipped) that way you know it will work with your B-series transmission.
I used to run this with my ITR engine + Cusco LSD (B16 ring gear pattern) many years ago and it was awesome, great mod for the road course or just spirited drives down the freeway. When I turbo'd my car 2 years ago though I knew the ratios would be too tight given the spool characteristics of the turbo so I went back to a 4.4 final drive. I highly recommend it for all motor applications, it will completely transfer the acceleration of the car.
Please note that there are some very minor rust spots on the differential side of the ring gear and lower portion of the counter shaft. As you can see from the pictures they're fairly insignificant. I mention it here to be upfront about the condition of the gears. It will not affect the performance of the gearset what so ever.
$400 shipped (add another $40 if you want the stock B16 differential included so that you can run it with an ITR or GSR transmission)

Pictured below is the side of the ring gear that contacts the differential and the side of the counter shaft with the area on the top used for staking the nut

Based on this thread: https://honda-tech.com/forums/transmission-drivetrain-127/gsr-internals-into-ys1-case-3198091/
It sounds like hydro gear stacks work in the cable transmission case just fine.
