SureGrip?!

[BROCK]

We bought a project 64 Cuda for my wife & plan to SCCA race it.  It's just a rolling chassis. 
So far the only mod is an 8.75 rear that is supposedly a suregrip.  With the rear lifted off
the ground & either tire held fast, the opposite tire will only rotate about 0.25 inches.  Is
this normal for a suregrip or could it be a poorboy spool?  The suregrip on my Charger is
b/o so, I have no experience here.

Is it a cone or clutch SG unit ? Either way i would be pulling it to see what's going on inside.

Thanks for your answer.  The car came with this rearend installed, so I'll have to tear it down for an
inspection. 

How do tell a suregrip when junkyard hunting?  I always heard that if you turn the right side the left
will turn in the same direction, which this rear does.  If the left & right turn in opposite directions, it is
an open rear, right?

You would be correct on that sir...

    Same direction = sure grip....opposite direction = open
