73X did the hard part of finding part numbers to work,
Anco 41-01 wiper arms and 31-13 wipers,
but when i got the parts home and put together i wasn't happy with the sloppy fit between the metal arm and the plastic J
so i got to looking at it, and started taking it apart.
where the plastic angle adjustment piece connects is thinner and narrower than the actual arm. this is the source of the slop. I removed the adjuster screw, and the plastic bits and test fitted it to the wiper arm. The fit was much better.
since the arm was adjustable for length, i opened the lock and slid the arm out an extra inch and a half or so to make up the difference in length.
The hole in the plastic J ended up about 1/2" past the hole for the angle adjuster, so I drilled a new hole in the wiper arm with a 9/64" drill after marking it with a sharpie and center punching it.
next I used a 7/64 drill to drill through the back of the plastic J.
then i was able the thread the original angle adjust screw into the plastic J making a much more secure connection.
the next modification to the wiper arm involved it's mounting method. Stock involved putting the ferule on, then the nut both with lock tite, then snapping the wiper arm over the ferule and relying on a little spring to keep it on the ferule.
I decided to reuse the factory barrel nuts.
to do this, I put the wiper arm in the vise, center punched the onside top of the serrated cap, and used a 9/32 drill through the top of the cap.
Next i used a small socket and the vise to push the ferule far enough into the serrated cap that the barrel nut would reach the threads.
The wiper arm re-installed just like a stock piece, and allowed for a little wiggle room when trying to line up the wiper with the motor.
Looking at the finished results I'm happy with the new arms, and the rigid hold the modified J has on the wiper.
