Hand controls for disabled?

My dad had hand controls on this very Dart in my picture-thigy-ma-jig off to the side there<<<<<<<<. A place in ,I believe , Mentor Ohio specialized in them.Mobility Specialties maybe?????? was the name. Sorry I don't know for sure as my dad has been gone since 2005 but let me reassure you -he hand hand controls all the way back to the 70's on his cars(they were all Mopars too)and the cars retained the ability to be driven without using them also. Amazing man.my dad.........
