how to tell if dodge dart is a swinger?

put the vin number into a decoder, or look at a site that breaks it up and explains it for you...

My 1970 Dart is a "Custom" which that year was the high end model, but the next few years the "custom" was pretty much the 4 door sedan slant 6...

Anyways, the vin number will tell you, and it should say on the title...

Some years, swinger just meant 2 door hard top really...
