Windshield Wipers

I have 1973 dart just replaced the wiper motor jump into car to find a bushing linkage siting on my floor mat. I am assuming this came out of the driver side linkage. Question do i access that piece from the instrument panel as well? I am unable to test it right now to hear if it is making noise because motor is out of car with no power. Ty

Yep, Many service manuals are free downloads, including 73. The 73 inst' panel isn't the most difficult to remove but step by step instructions for these type services will help.
