Default C4 Throttle body differences.

Looking at aftermarket throttle bodies, I notice that they are often broken down into specific year groupings, 85-88, 89-91,92-93 and 94-96.
What are the differences between them, they all look the same from the pictures, I would assume the stock units are different as well?

Most of the differences are how the throttle cables hook up and the vacuum ports. :chevy

That's what I thought. I have an 87 and there is lots of play in the shaft, the engine is stock so I just need a replacement. I wanted to make sure I pick one up that will work.
