Volvo Headlight wiper - Location report

The original headlight wipers seem to have run out or will at least be in the near future.
After my local Audi dealers could not get any more, I looked at different Volvo headlight wiper blades as an alternative.

From the size and recording three different variants were in question.

Volvo (740 to 1990, 760, 940, 960)
Length: 160 mm
Part No: 274430

Volvo (740 from 1990, 960-II, S80, S90)
Length: 140 mm
Part No: 274431

Volvo (S80, V70-II from 2000)
Length: 125 mm
Part No: 274433

The original wipers have a length of approx. 137 mm and are symmetric.
274430 with 160 mm are definatively too long and hit the bonnet. The original wipers also make this a bit.
274431 are also symmetrical and almost identical to the original wipers. Visually no difference actually detect
274433 are asymmetrical and somewhat shorter. Fit mine even better than the originals. Especially when these are rotated 180°.

Also a picture with the different models.
