Hi, I have a Detroit Locker ( 31 spline) Diff head assy for sale- 'N' Nodular housing & IIRC Daytona pinion carrier, 3.5/1 ratio. The Locker unit is one of the earlier parallel spring versions. Needs a strip & clean- been sitting in the loft for too many years. Was going to strip it & use the locker in my transaxle, but then I would have some spare bits lying around that the missus would swoop on for her daytona which would mean more work for me...( Its OK, I have a spare 300zx diff she can use in that..)

$850.00 the way it is or if you want to supply an alternate R&P ratio & bearing kit I will set it up with those for another $100.00
