9" Posi

[LT1Nova]

I am looking for suggestions on what type of posi to use in a 9" ford rear. Auburn, TrueTrac, etc.
Anyone care to share expirences?

Any sources with good pricing?

If someone has a good condition used one posi unit or center section I may be interested. I am looking for 31 spline, 3.25 gears.

A bit depends on your planned uses. 1/4 mile drag? Road race? Street only? a mix of all?
Drag/street - detroit locker
road race /street - Torsen or Eaton
Street - eaton
Mixture - Eaton

The Nova will mostly be used for performance street and occasional drag race use. Not much for road courses here in South Dakota although there is one south of Omaha that I would like to hit sometime.

I would say that the Eaton would be the best suited for those needs. Quiet on the street, works well at the stip, and would be more predictable if/when tyou road course it.
Not sure what preload they make for the 9", but they make a 400lb and a 800lb for the 12bolts.
