Everyone that knows anything about Fords knows that Trac Lok is Fords version of a Posi rear end and there is indeed clutches in it.
Just because your car might have an aftermarket unit in it don't post here saying something to be a fact when you are the one that is wrong

Be the "banishment" issue as it may, do you now understand that either you have clutch plates in your differential--or you do not have Traction-lok?
As to Positraction; that is GM's trade name for their clutch type limited slip differential introduced in the early 60s. Over the years the term "posi" has become a generic reference, used by those who know no better, for LSD's in general--and by those who really don't know crap to refer to locking differentials.
I suspect that "the guy" is one of those who really doesn't know crap, and that what he meant by not a "true posi" was that it is not a locking differential--which is true, that's why it is called a "limited slip" differential.
Also, as it is a Ford product it is not possible for it to be a "true posi" anyway--that would be a trademark infringement...

Cliff notes: If your diff doesn't have the clutch packs it has been modified by the previous owner and no longer has the Traction-Lok limited slip differential that it was originally manufactured with. Bramas was trying to explain this to you, but you're stubborn, and cliffy has a lot more patience than us and did it in a nice way.

Anyways, I agree 3.73s are the way to go. And just so you know it was most likely your right tire not your left. When I go straight or left spinning, both tires light up, BUT when i go right I really gotta throw it or get on it hard to get both to light up or its just the right tire spinning. As you can imagine I usually just go left...or straight...or I don't do it all and save my tires ;P lol

The Traction-lok system is a clutch type LSD (Limited Slip Differential), which works by using the side thrust generated by the spider gears to load and "lock" the clutch packs--the key word here is limited.
The magnitude of the loading on the clutches, and therefore the "locking", is directly proportional to the torque being transferred through the differential--I.e. more torque = more loading of the clutches = more limited slip.
This all works best when both tires have similar grip, and during hard straight-line acceleration. If either tire has a lot less grip than the other it will spin as the loading on the clutch packs will be significantly unequal. Also, once one tire does break loose (meaning it suddenly has a whole lot less grip than the other) the whole thing breaks down until the forces, loading of the clutch packs) once again equalise.
There are also other scenarios where the load/friction on the clutches in unequal (such as while turning when one set of clutches is already slipping) and you will get a "one wheel peel".
The short story is that an LSD is not a "locker" and will never be a locker--over the years I have probably seen more clutch type LSDs being unnecessarily rebuilt, than I have being rebuilt because they needed it.
