Curious to know what differential and gear ratio others are using in their bucket.
What differential are you using? Open, LSD, or a Locker?

Indycars....does the traction lock make a lot of clicking noises when you turn? I just bought a Ford 9" 4:11 traction lock carrier. The guy told me it was pretty noisy when turning. Curious to know how you like it.

No, I've never heard any noises coming the rear end.
The only trouble I've noticed was usually on the highway and entering long sweeping turn the car would shift when the clutches finally started slipping. I doubt anyone else would notice, it was very slight. The fluid had never been changed since 1979, so I changed out the fluid and added two bottle of friction modifier. This fixed the problem completely.
Ford 9" Gear Oil Replacement and Cleaning the Interior of the Housing
I have never changed the fluid in the rear axle since I build the TBucket in 1979, so it was time to do so. I talked with GRT1999 (Gary) about a small problem I'm having where the car twitches a little entering a long sweeping corner on the highway. It's happens when the clutches in the...

Friction modifier really does make a difference.
Recent lurker. First post:
A Trac-Loc isn't a "Locker" like a Detroit Locker is. The Trac-Loc is a typical Clutch-Type LSD.
A "locker" like the Detroit Locker is a "ratcheting" diff, which would likely make clicking noise on turn. I honestly do not recommend this one for a T. It will be happiest going straight or sideways; they are good for dirt, drift, or drag.
My all-time favourite is a helical "torsen" (torque-sensing) differential. These use a crazy arrangement of gears (no clutches!) that work absolutely seamlessly. They don't like one wheel off the ground - they will act as an open diff if they do. I have a torsen-style "Detroit True-Trac" in a turbocharged-LS '61 Chevy pickup, and had one in a V8 Chevy Sprint (Pontiac Firefly up here in Canada). They are very nice and very forgiving.
Clutch-style like the Trac-Loc would be a good second, as would an Auburn "cone-style" LSD. Avoid a Locker on such a light and small-tire'd front end.
