I had no idea Doritos were so macho

To hell with generic names. I am correct either way, Posi-traction provides energy to both wheels evenly to the rear differential while Limited Slip does not.

That looks to be a '68 Fastback but depending on the time of year it was built, LSD was still an option and not standard on the Mustangs. The late '68's had it standard.

The studio probably cheaped out and took the no traction option. Doesn't matter who invented it, Ford uses it as SOP on all their rear wheel drive cars now.

I cannot speak for the other manufacturers who use Posi-traction as to when they or if it's standard equipment.

hey, that's fine with me. I learned decades ago that women are always right, so I will defer to your wisdom.
