I'm working on the rear end that came out of my GT/CS and the tag says: WCZ-F1 3.00 8FB 931. Is this the correct tag for my GT/CS? The rear end was replaced with an unknown rear end to tow it from the wrecking yard. How can I tell what the actual gear ratio is for the rear end?

WCZ-F1 - 1965-1970 Mustang
3.00 - 3.00:1 conventional axle ratio (not traction-lok)
8FB - 1968 June 2nd week
931 - Plant Code

Looks like it could be right depending on the build date of the car.

That could be the correct rear end for your GT/CS if you have a small block.
That is an 8" ring gear with 28 spline axles.

2 months before or after the build date?
