Windshield Wiper Question

With the XJS, while the ROM specifies parking on the driver's side, there is a lot of variation - mine park on the passenger side, which is better for visibility. However, both do a full 180 (okay, a little less) sweep - the driver's side wiper does not clean right up to the edge (a 90-degree sweep). So whichever side they're on is not going to make much practical difference.

My RHD XJ-S has the wipers on the left. A friend's same age LHD has the wipers on the left. Another 1990 in the next village has them on the right.
Iirc there were several changes in the cycle... XJ-S PreHE had the unit in silver/chrome-look and they sat IIRC on the right. The HEs had them on the left. Facelift models again got them again on varying sides.
As nearly all cars have had a new setup somewhere along the lines and they seem to be interchangeable, people have "mixed and matched" as they want.
I remember reading this but can't remember where.

They are essentially mirror images of each other. If you switch, the drivers side will get wiped exactly as your passengers side gets wiped today. Imagine it as a simple mirror image. The wipers are symmetrical so that RHD cars had wipers parked on the right, whereas LHD cars had them parked on the left.

VEE. I think its the other way round LHD parks right (passenger side) RHD parks left (passenger side) But as you can see if you google XJS photos it seems random.

That explanation is bandied about quite often in Jaguar discussions and, personally, I don't put too much credence in it. I'm not saying that impromptu substitutions *never* occurred but I seriously doubt it happened regularly. I just don't believe that Jaguar, by the time the 1980s-1990s rolled around, was so backwards in production methodology that such off-the-cuff practices were commonplace.
If you go to the parts catalogs you'll see multiple variations of wiper mechanisms based on VIN breaks and RHD vs LHD. If we were to study the variations and compare them to our cars...considering build dates, VIN breaks, etc. I'm pretty sure we'd find some logic or pattern.
Speaking more generally, service TSBs (I have loads of them) also often lend logical explanations to production changes....many of which applied to only certain cars, or were market specific.....which to our eyes seem random and are commonly explained away by asserting "....they just grabbed whatever they had off the shelf and used it".
Having spent 30 years in dealership parts and service departments I naturally came to know and speak with many "factory" representatives/employees. I can assure you that they didn't always know the right answers and often perpetuated inaccurate information.....either out of ignorance or convenience. Granted, I never worked at a dealership representing Jaguar but I doubt that Jaguar would be much different than all the others in this regard.
Sorry to be contrary....and I'm certainly not asserting that I'm correct in this particular instance, as I haven't researched it in depth. Just tossing out my two-cents

If anybody cares to research this for theirown satisfaction, my 95 4.0 coupe is LHD and my serial number 199271 build date1/95. My wipers park on the driver’s side which I want to change to parkpassenger side. It is simple to change the park position by rotating theposition of an arm at the motor 90 degrees. Then replace the wiper arms with aset designed to park the other way. They are different the bend of the arm isin the other direction. I am looking for a right side park set. If anyone wantsto trade my left park pair for a pair of right park, just let me know.

Supply problems, using up of stocks of components, etc etc all account for a great many small differences. If a wiper set fitted, and that was all there was, even if originally for a different market, in it went. About 4 years ago the JEC had an article, or even a series of them, on this topic of wiper parking, and they concluded there was absolutely no consistency at all in the matter.
