If you're asking in reference to your 82 TA, and you're still using the original ECM, a simple answer might be just to put something like a 2.2K resistor in place of the EGR solenoid. That should be enough to prevent a check engine light.

Something you should be aware of, is that normally when the EGR is expected to be on, there is generally more timing advance than what would otherwise be needed, so be alert for part-throttle pinging. The '82 code, and carbureted fueling, is probably sloppy enough that this won't be an issue. But if it is, a little chip tuning, or a reduction in base timing may be in order -- or just run a cam with more overlap

If you want to get into the ECM code, over on Craig Moates' website, there's a $40 hack, that applies to the later CCC cars, and a couple of bins there from the GM ZZ4 HO conversion, which don't use an EGR valve. Doing a search for "CCC" here on the PROM forum should net you more details.

If your car is a crossfire, rather than CCC, disregard the previous paragraph.
