I have a Detroit locker for sale. 26 spline, will fit 7.5- 7.625 10 bolt rear. bearings look good. came in a car that I just bought for parts I would use it but I just installed new 28 spline axles and locker in my car before I got this. car had 373 gears, gears not included with locker. Locker does not look like it has many miles on it. would like $350 plus shipping. this locker goes for $580 at summit racing
