Do the wiper arms go through the "parking" procedure, or just stop when you turn off the wipers?
If they do the little dance before they stop, then the system is parking properly, and you need to reposition the wipers on the shafts as noted above.

In all honesty I've never turned them on, not sure what would happen with them so far in the wrong place
How do you do that? Is there sone kind of procedure to get them off the shaft?

When you turn of the wipers they should continue and park. Looking at the picture the passenger side wiper looks good and the driver side high.
Being a 69 there should be a hole through the frame just above the pivot shaft. Lift the arm away from the glass and put a nail or allen wrench, or drill through. Then push arm down gently and pull up on the assembly at the shaft, sometimes takes a little assistance.

Yes, there SHOULD be a Park Switch on the wiper motor that instructs and orchestrates the wiper blades going into a "Park" position. Lower and out of sight when completed.
There usually are some ball socket joints where the horizontal linkage attached to the individual wiper arm sockets (to make them wipe as the linkage moves horizontally). Seems like there is some sort of adjustment where the two sizes go together? Perhaps the FSM has some instruction of how the wipers are assembled and how the washer nozzles are aimed/adjusted.
Just some thoughts,

any pics of this procedure? Pictures always help thx!
When you say frame you mean the window frame?

This is NOT a park issue, there are NO adjustments. The arm is simply installed incorrectly. Keep on track
FYI, wipers like to hang up on the trim, go to the right wiper and poke it down, the other will go with it, just not enough, it will need to be repositioned.

The concept was transmitted, but we also added some details.
For " modern" cars, the wiper arms are secured to a round shaped "post" that rotate - being driven from the wiper motor and transmission linkage under the cowl. You pop the black plastic cap on the arm and there is a nut under that secures the arm to the post.
In the 70's, they used a mechanical friction fit for securement of the arm to the post.
The wiper arms are spring loaded to keep the wiper blade on the glass and lock them on the post. To remove the arm you have to relive this spring tension. That is one of the comments above - find a small block of wood to put between the glass and the blade. It will result in the wiper are looking like the shape like a hockey stick.
The other comment from above is to insert something like a drill bit or a nail near the pivot joint of the arm to the "end cap" at the end of the wiper arm (circled in red in the pics) to keep - maintain retain this position, you will see a small hole, this is where you insert the nail - see photos
Now, here comes the fun part. Based on the year of the car, if you look at the end cap - which is more of a "U" shape, there may be a very small tab on the right hand side. With a small jeweler's type screwdriver, you have to move the tab away from the cap, think of the tab moving from 12 to the 1:30 - 2:00 position.
This is a crescent shaped retainer that "Locks" the wiper arm onto the post. This is so when the wiper is working, it will not work its way up the shaft and pop off the post. This was the stype on my 1978 Chrysler. Some years have this lock, some do not. I do not know when Chrysler stated using this lock type of arm. For my 1969 Chrysler, there is no locking tab and that is what is shown in the pictures attached.
The post the arm sits on has a very fine knurled machning- notches that provided a tight friction fit between the post and the arm joint. Once the lock is out of the way, (if you have one) you can work the arm off the post. Be careful as the wiper arm is spring loaded and will want to straighten up - go back to its original potions if the nail or drill bit come out during the removal process.
For the driver side - there is also a secondary arm that connected to a raised dimple on next to the post circled in blue.
There is a neat tool for getting under there and forcing the arm up off the post. I bought one and have used it several time, in my opinion it is worth the money. ; )

Maybe I'm simplifying it too much, but why don't you try them anyway?
If the park feature doesn't work, and it probably doesn't, you can then get the arms down in the lowest position and then if you want to move them, go for it.
My thoughts are if they aren't in the lowest position, and you move them lower, then turn them on sometime, the results will be the arms crashing down and maybe some damage.
Yup - agreed. Leaving them positioned on the pivots as they are won't damage anything, and you can see if they work properly or not. Spray water on the windshield before you turn the wipers on.
See what happens when you turn them off, and take it from there.

Ideal procedure.
Remove both wiper arm assemblies.
Turn wipers on, let run, turn off.
Place a cable tie on each shaft as if it was a wiper assembly in what you think is the correct orientation.
Turn wipers on and observe operation (on restorations where you are first testing this is to confirm the arm is on the motor correctly). You are just confirming the park operation works and the arms will be going back on in the correct position.
Put wiper arm assemblies back on and test.

99.99% sure there is nothing wrong with the park operation, if it was both blades would be up in some degree the same.
I just went through this last week.
I have done this on other cars.
Focus.

Wow- perfect timing for this conversation as I was replacing the wiper blades on my 72 Fury wagon ( Sport Suburban) this week and noticed - yes- 1) The wiper arms do not rest on the aluminum/stainless spot beneath the hood but then I realized the Bosch Micro blades I bought might sit a bit too high to fit under the hood so in reading this article- I was wondering- any recommendations for what wiper blades are recommended and so while in the off/resting position under the hood that they'll fit?
Thanks
Frank
Thanks

Knowing how "modern" wiper blades are sold as a unit to fit current models, with attachments to adapt them to older cars with "hidden wiper blades", seems like @Big_John has mentioned some "snap off to fit" INSERTS for the OEM wiper arms, from NAPA?

See pictures in post #10, there should be a hole (circled in picture).
Raise arm, insert a nail in hole and lower arm firmly (just not hard), you may need to help them off with a small prybar (protect surfaces).

Both sides should have the hole.
