I just put a Detroit TrueTrac in my Cuda, which was recommended to me over other clutch style posi units for road racing.
"TrueTrac differentials are unique in that they increase traction but do not affect steering or wear out prematurely; these problems are common with limited-slip differentials that use clutch plates and springs.
TrueTrac performs like a conventional differential, until there is a loss of traction. Only then will the power transfer occer - when it is needed."
(Just happened to have the TrueTrac owners manual on my desk.)
Cris, are you saying the splined side gear which the axles slip into in the diff has movement? It seems to me it would take a lot of movement of that gear to create such angles at the tire (since they are so far from each other, and they should be located at the ends by a bearing). Also, in the exploded view of the TrueTrac it looks to me like it does have shoulders to locate the side gear. I also just looked at a similar helical torsion diff at my work and the side gears are also located by a shoulder.
I would think the outer axle bearings and how the axles are retained would be more of a concern. Please let me know what the results are, I like this stuff!
