Opinions please!

My 69 HT (see garage) has a Detroit Locker 9" rear (the silent type) that actually works very well - for a Locker!
My issue is that I use it for spirited road driving and am looking for another diff that won't be as tricky out of the corners. A Locker is great for drags, but when I really come on the pedal out of a corner (est. 380-400hp @ the wheels) the rear end gets very loose and I have to either powerslide thru or let go of the pedal to disengage the Locker and get full grip back. No PS so it takes a bit of holding on... Can get a bit hairy!

What's the opinion on Detroit TrueTrac for my application? Any other good suggestions?

the true trac is just a locker with lighter springs for less noise. you will still have the same tail happy situation as with the locker. you can reduce that tail happyness somewhat by either eliminating the rear sway bar, or(if you dont have a rear bar) installing a larger front bar(1 1/8" should do the trick).

The TrueTrack is a limited slip...?
It's this we're talking about: http://www.detroitlocker.com/DT.htm

More info:
I already have a 1 1/8" front sway bar, no rear. 620 front springs, 4½ leaf rears. Global West upper control arms (neg. roll), Spax racing adj. shocks set to 11 out of 14 (14 hardest) both front and rear. Lowering comes out to 1 3/8" total.

It should give you better grip around the corner, without the on-off locking that a locker does, but if you overpower it it'll do the same thing that the locker does - spin both wheels.

On some other forums the search button does not work very well, Stangnet has one of the best.

Hehe, OK case closed. That elusive search button again...
Guess it's a TrueTrac for me next time I'm in the States.

Don't think so. The TrueTrac doesn't use a ratchet mechanism like the the Locker. It uses a worm gear, which is also different from other LSD like TrakLoc which uses a clutch. It will be my differential when I modify my 9".
