Detroit Tru-Trac
You mention that you have a stock 95 rear end (differential). You don't say if you have a Trac-Loc or Open diff. Both were "stock" in '95.
With the kind of hp/TQ that you'll have, you should probably go with something stronger than a Trac-Loc, in your new alum. case. If you do in fact have a Trac-Loc & want to keep/rebuild it, the alt. stacking method looks like it will handle more TQ than the Ford stacking method.
I will never recommend a Regular Auburn Cone, which I have. I can feel it slip about 1.5 revolutions before it grabes. The Auburn PRO has more bias pressure that the regular, & is more suited for SC's.
When I replace my Auburn Cone, It'll be with a Detroit Tru-Trac. The Tru-Trac is a Worm/Wheel design (clutchless). Allows full differentialization around corners, but locks solid when you race. It's suppose to handle at least 500 hp!!!!!
The OEM 8.8" Trac-Loc in SC's is a Medium Duty unit. I tore up 2 of'em (both with 30K mi. on them), before I put the (regular) Auburn Cone in.
