Bob,
re: Torsen, I'm not exactly sure, but I know the Tru-Trac is a "throw-out" worm gear engagement...no cones or clutches

I think "Tru-Lok" is a different concept from "Tru-Trac"...but what the hell do I know...
I found a brief (very) explanation at...
www.southernhighrollers.com
"Tru-Trac" had a website somewhere but I cannot find it.
BTW, doing engine and drivetrain work is a hell of a lot easier than hanging fiberglass doors, my current nightmare.
...should hav' bought a ERA or SPF to begin with...this building from ground up has cost me years of hair loss.
