Well, I got the wheels. Pulled off the '97 Tahoe Z71 wheels.

And I got the late-model wheels on.

But, I do have a question for anyone that knows. Here's a close-up of the wheels that I put on.

Now here's my question. The guy the wheels came from say they were off of a 2000 Chevy Z71. But, these wheels are different than the ones on my dad's 2000 Silverado. Instead of the half-circle where the spokes connect to the wheel, my dad's wheels have 2 bars attached. Does anyone know any differences? If these were actually from a different year or for a certain trim level?
