Seeking Correct Pinion gear for 4:11 LSD

All,
I know this may be more appropriate for the Want to Buy forum but thought the Race Guys may have these gears with the diff swaps for the various tracks, not that having a corrected speedo is imperative on the track.
Anyone have a spare pinion gear to correct a 1600/2000 speedo for a 4:11 setup. Orig gear was a 3.91
Tire size is 205/55/14. Running 140mph speedo but plan on swapping to U20 160mph version.
Thanks

That might be hard to find as us race car guys dont run speedo's. So....its not something we would normally have or care about.
I would look for a silvia owner or Stan for that kind of part. Its going to be tricky.

Nissan likely still has the gear, the carrier is another factor. I found one at Rallye but I don't' think they have any more. Even with the correct gear, my odometer is pretty close, but the speedo is more than optimistic. 7200 rpm in 5th has me doing 170+... I think not.

Nissan part 32702-58SXX where xx is the number of teeth (includes carrier).
As I have oft mentioned before, you have to KNOW what is CURRENTLY installed BEFORE you can decide the number of extra teeth you need. It is not just based upon the diff, wheels, tires are also part of the equation, but ya gotta know where to start from.
Since the ROADSTER carriers are NLA, using the above part number requires that you cut a groove in the carrier to shift the position of the carrier to accommodate the larger diameter pinion gear.
Check the tech wiki for Ross' chart. Search for speedo
It's a tad tricky to splain in writing, so feel free to call.
