HELP am I missing something here? Throttle body related.

[country_boy13]

So I picked up a throttle body yesterday at a parts yard off of a 90 convertible mine is a 91 convertible I got it for the TPS sensors but when I got home and started looking at it it has a bar with an adjustment screw going to the first set of butterflies that mine does not have. It looks like this is the only thing that would open the butterflies or is that the dashpot's job? The dashpot's are also different. So I guess my question is. Is this piece missing from my TB or do they come with different parts?

Here's a link with a picture of what i'm talking about. http://s1259.photobucket.com/albums/...ile%20Uploads/
