Searching to purchase a carb spacer for 1982 Dodge Aries 2.2 4 door sedan

Too old, most of those are crushed. If a wrecking yard or EBay doesn’t have one then you might want to consider making one truck or tractor gasket material, you need something at least 3/8 inches thick. Not going to be easy,

I'm sure no one makes one for the Aries. Spacers are produced as demand warrants and the vehicle is for an enthusiast, like a sports car. I would simply tune up your car to have it run properly. If you really want to get ambitious, you can find out what carb you have and search for a spacer based on the carb itself, not the car. You can also try making one yourself using the current gasket as a template.
