Alright. So, the first thing you want to figure out is whether or not your car has a computer controlled carburetor. I think 1980 is the changeover year from non computer to computer controlled. (Yes, they actually had a computer controlled carburetor, as opposed to early throttle body injection. They're complicated, fickle, and, frankly, a pain in the...)
If you don't have a computer controlled carburetor, it's just a matter of weeding out the unnecessary vacuum controls and blocking off the EGR valve. If you do have a computer controlled carburetor, you'll need to get ahold of a non-computer controlled carburetor AND distributor.
The following link is an example of the computer controlled carburetor commonly used:
The only real difference externally from the normal carburetor is the addition of two plugs, one near the accelerator pump on the front of the carburetor, usually a 3 prong plug, and one on top of the carburetor, usually a 2 prong plug (shown in blue on the pictures)
I do not know of any way to convert that to a non-computer controlled carburetor.
I did this same conversion on my '85 olds wagon about 10 years ago. It's not terrible, but you need to have a timing light around if you're going to remove the distributor. Also, a vacuum gauge helps when tuning (nothing fancy, so long as it reads to about 25 inches/1 bar vacuum).
