It's a three piece Roadster 5 speed transmission with an L series bellhousing from an early 240z
Gear ratios:
2.957
1.858
1.311
1
0.864
Bellhousing fits L series engine and is very rare
The short tailshaft housing makes this the only 5 speed transmission that will bolt into a 510 with factory mounts and have the factory shift hole location. No cutting or modifying of any kind to get this into your 510!
Install the Nismo close ratio gear set and you will have a competition 5 speed for L series that is FIA legal for vintage racing.
I drove around with it for a while, but it had some bearing noise and a stiff 2nd gear synchro, its useable as-is but would be best to refresh it.
Included is the proper slip yoke and driveshaft that bolts to the trans to fit 510 sedan
Asking $500 +shipping 510realm price!
