60 Wiper arm Differences?

[FL cruiser]

Looking at SOR's site, they show three different wiper arms used depending on the manufacture date. 8/80 to 10/81, 10/81 to 10/82 and 10/82 to 1/90.

There is only one part# for the main linkage where the arm attaches 8/80 to 1/90

So I'm wondering if other year wiper arms will work other than my application (9/82).
Are there just style/cosmetic differences in the arms, or are they totally different.

Just curious how particular I need to be before I start hunting a used one.

Thanks!

They all fit, just look a tiny bit different/have different springs.

The windshild is the same for the 60 and 62's if that helps

I just used a local auto parts store replacement 17" (I think?) and they work great!
