Konica Auto-S frame alignment

[chikubi]

Hi, I have a Konica Auto-S that is in near perfect condition and takes great pics. Just recently, though, I noticed that the images are somewhat shifted off-center to the right, even though they were centered when I framed them originally. The camera has auto parallax correction built in so it's not just a matter of poor compensation on my part when framing, so I was wondering if this is something fairly common that can be adjusted? And if so, what's the general procedure? I have no problem working on the camera - I've done rangefinder cleaning, vertical adjustments, etc. before, but not sure about what this might involve. Some sample pics are below, any help is greatly appreciated as I really like the camera otherwise.

First shot, each post was lined up on the L/R frame lines in the viewfinder.

Here's some car show pics where you can see the right-hand shift as well. All the cars were framed centered in the viewfinder.

Lots of views, but no suggestions, so thought I'd bump it.

These finders were never super accurate. Something might be slightly out of alignment but I think the best thing to do is allow for the shift when you frame the photo. I have an Auto S and from memory I think it would be hard to adjust the moving frame sections.
They are great cameras though.
