Help rebuilding 8 3/4" Sure Grip!

You're on it Terry, kewl, I saw that article in Moparts already, it's pretty basic info as far as the cone type info goes. I like the last sentence in that tech info."Some level of lock-up" they say, lol.

Machining .030" off a surface that's already worn .005" ish and replacing it with .030" and likely weakened springs.
It just doesn't quite cut it IMO.
Info on the clutch type is easier to find, but yet it seems like there's more
"Cone" type rears then "Clutch" type.
Finding specs would help many (70%) 8 3/4" owners, rebuild there diffs.

When new the "Cone" worked just as good as a "Clutch" type, IMO.
