Neutral safety switch harness for 70 A body Duster

Does any company make them for A body cars, are they reproduced? Are some other Mopar's harness compatible? Like this one for a 68-70 B Body. My Duster didn't have one when i got it and I've always wanted to make it right. it's a little scary being able to start it in gear.
