Redline Heavy Shockproof is what was recommended to me by Ted Harbit; I've used it without issues in the 3.31 TT unit in my '62. No friction modifiers required for use in a limited slip.

I believe that any GL-5 rated oil with the appropriate friction modifiers would work; I just consider a good synthetic cheap insurance.
