Hi Gary,
I said I would get back to you and I may have found an answer for you.
It took me a while to find a problem with the wiper mechanism, everything on your truck is the same as my 4 door and my Van, the electric Motor conversion, I assume is the same, if you have Craig Brockhouse's Electric conversion motor, they aren't $100. On all of my trucks right and left are parking correctly and have exactly the same movement, they work equally the same with no slop all of the way equally across the windshield on either side. So here is a possible thing to look for, on the ends of the linkages on both ends they all have a great rubber mounted sleeve bushing, I pretty much ruled that out because they have no wear at the speed that they are used, and living here in the AZ oven, I have had no problem with the rubber in the bushings, the shaft ends can not be a problem because the wear factor on a shaft can not cause a problem, the inside arms are different the passengers side is 19" long and the drivers side is 24" so you could not have reversed them, next thing I checked is the channel for the wiper motor to make the movement, that is also made easy because before setting the motor the channel is marked top in the channel, it can only go into the channel one way because of the index slot. It is also not a problem of reversal of the shafts, because the wiper arms are parking to the inside, not the outside. So what else can it be?
I remembered why I had to have the new splined acorn wiper arm mounting adapters made. So I found a used acorn and put it on a wiper shaft, it has a tiny bit of slop in the slot, against the shaft, it can rotate a tiny bit on the shaft. The new acorns have no slop, the acorns are made of aluminum. so I mounted the used one on my 4 door, and I had similar problems that you described, then I switched them a new acorn from the passenger side and the used one on the drivers side. Now the left one was not the same. It doesn't make sense how can a tiny bit of slop cause that much difference, it is because the length of the wiper arm and blade magnify what a little bit of slop at the shaft can be causing at the wiper arm.
Next I went to the wiper arms at the blade connector, there are lots of wiper blades, but the problem is finding them. I have been using Trico blades, so I decided to try a 12" plastic China wiper arm and arm adapter, on the drivers side, and after my test results, I can say they miss a lot and they are not for an FC. I can tell you what a P.O.S.
So my conclusion is this go Trico. I recently put together the pieces that Ben of CA was looking for, and I had told him that the Trico blade refills were still sold at the NAPA warehouse, I was driving by my local NAPA so good thing I checked, I asked the new guy that I had never seen on the counter for Trico classic 12" wiper refills, for Ben and decided to get a few for me. The guy at the counter says we don't have them any more. Next I asked him for Trico 12" wiper blades again, same answer we don't have them any more, NAPA doesn't have Trico products anymore.
So I went to where the blades are on the rack and there they are in the book 57-64 Jeep FC, he was correct they are not sold under the name Trico classic, they are now repackaged under the name of Napa Vintage with the same part number.
I hope this is the ssolution / answer to your problem, I have the new Acorns.
