There's an Iroc Z28 steering wheel that has three lines on each spoke. I didn't even know and hardly see them. Are they rare? I heard that they were only available in the early model Camaros. Here's a picture of what I'm talking about.

 

They were used on all Z28s and IROCs from 82 thru 89.....looks like it is in good shape.....

 

I think the three lines are 82-84, and the two lines are 85-89.
