Quick update. . I used a zip tie to secure the long linkage arm in place Very carefully w both linkage arms in place and the washers resting on top of wheel pins, I eased the 2 clips into the grooves w the spring securing them. Cut the zip tie and did a another test w/o the wipers mounted. Replaced the original enormous radio which obscures seeing anything, and breathed a sigh of relief.
I would tell anyone to check the allen lock screws on the motor's pivoting wheel ... that wheel separated from the motor w the linkages in place..
Not a fun job to redo.. I will also use products like Rain Block on the windshield.
Trying find better quality wiper arms and especially wiper blades.
