Thanks FED..
Yeah, seriously thought about that..!

A new Posi would be twice the cost to rebuild but simpler quicker to install.
PN for the Springs is $90, Carbon Disks another $119.00.
It is still good for the street and drag racing.

Have the option keeping it for a street project, the 94 Caprice SSuperwagon being set up for towing or sell to a B-Body racer.
Should be a wash after selling it.

In past have rebuilt a 12bolt Moroso Posi with new Springs from Al's Differentials.
Built a clamp tool out of 2x4 and to force them inside the cavity with a hammer.

Eaton has three types of clutch service kits.
OE, 18 disc (standard), 24 disc (high performance), the modern day, high tech 14 disc carbon fiber design.

Last night studied all about their characteristics.
Still need advice on which of the last 2 to buy.
