Wiper Switch Conversion, Different for Early Cars? What am I missing? Options

[BeatNavy]

So today was going to be a good day to do the wiper switch upgrade as my car's up on jackstands for brake issues and probably will be there for a few days. I was following the Pelican Article which describes itself pertaining to '74 (I've got a '72). But I've read through a lot articles on this, and I don't recall seeing any distinction between early/late cars. I ordered this 924 switch (part number 111953519G as per the article).

Anyway, once I started the process I ran into several issues which have me stumped. First of all, the quality overall seems sketchy. I had seen the caveats on the quality of this one, but even then the quality seemed suspect to the point that I'm not sure it would work at all. Then I ran into the following additional issues as annotated in the picture below:

1. The layout is different than what I had seen in other pictures, and the wire colors did not match the old switch. There's a contact anchored to the outside of the switch that I have seen in other pictures on the inside....which wouldn't bother me except...

2. ...it's held in place by a bolt and nut going through one of the holes that should hold one of the four metal sleeves that hold the turn signal and wiper assemblies together. WTF? I assume that this contact is necessary, but it will fall out without that bolt in place.

3. The actual holes in the metal piece through which the sleeves should slide were too small. I took a drill bit and by hand worked them wide enough so I could get the sleeves in, but it still makes me question if I have the right part.

4. Dog, recovering from ACL surgery, is no help at all.



Has anyone else been successful doing this on an early car with this specific part (from this vendor) and do you recommend a different part/vendor?

Thanks for your help. Winter's coming. I'd like to be able to clean the windshield.
