I have a low time R-190 Final Drive with 4.44 gears. The R-190 was a Datsun Competition part only. I believe all of them came with limited slip.

This gear is great for Solo II work. If you use the over drive 5 speed it does pretty well on the street.

'77-'79 5 speed = 3.83 ratio in fifth
'80 = 3.43 ratio in fifth
'81-'83 = 3.30 ratio in fifth

As you can see this can give the best of both worlds. Solo II or Solo I along with tracks days you can get great acceleration on track along with highway adaptability.

This unit uses the 240 mustache bar. It will also fit a 510.

Price is $850.00 plus shipping.
