8.25 limited slip, Rebuildable?

I have rebuilt at least 6 cone types, and adjusted them to my liking.
For street, and 295s,I like120 ftlbs of turning torque using 80/90 gear oil and the correct amount of GM Limited-Slip whale-oil additive. I used Ford side gear washers. Sorry; no pn. The old guy behind the counter always knows what I need.One of mine has a pretty thick stack of washers in it already, but it still works great behind my teener.Yeah I've cut that one a few times.
Behind my 367 I have a trac-loc 4-spider clutch-type.

Are you talking about the 8.25 or the 8.75? The 8.25 cones are a challenge to machine to say the least.
