Wiper Linkage Repair

For years I've been annoyed with my wipers; they flop around when the window is really wet and they don't park where the should. The left wiper
would hit the A pillar when it was really wet, park about 1"-2" from the cowl, and the right wiper would park at least 3" from the cowl. It got so
annoying that I hated using the wipers, and would manually park them after getting out of the car to keep it from looking "junky".

I took a close look at them during the engine install a few months ago, and found that the arm that goes from the wiper motor to the left wiper pivot
had some major play in the bushing. I searched hi and low for new bushings, but I couldn't find any. The next search was to find a used arm to replace
mine; ended up buying a complete wiper module assembly from a '94. Turns out that the '90 and '94 wiper assembly's differ quite a bit, so I ended up
pressing all the bushings out of the '94 linkage, and re-installed them into my old linkage. Another issue was that the hole in the arm (wiper motor to
left pivot) had oblonged, so I had to weld the edges and re-create a round hole.

After doing this, my wipers now sweep the same no matter how wet or dry the window is, and they park against the cowl.

I didn't take any picutres of this job, so below are some images of the '94 wiper module assembly to show you what is going on.
