Outer door handles.

66 Dart Wagon.

My drivers side outer door handle is toast. The button does not feel like it's connected to anything. Have to open it from the inside. It's a rat rod/surfer mobile kinda project. don't wanna sink tons of money into it. Rarely use the rear door handle. Are the back door handles the same as the front. Would like to but the garbage one on the rear and vice a versa. Also what other donor cars could I use for my door handle? Thanks.
