Wiper blade, spare side mounts positions (160B sedan)
 

After reviewing the judging standards and some factory photos, the vacuum wiper blade appears to be towards the passenger side in the assumed off position. Ours is to the left. Which is correct?
Also, the side mount wheels appear to be tilted inward very slightly in a '30 roadster factory photo towards the top of the cowl.

Original wipers park towards the center of the windshield. My repro parks to the left like yours. I actually prefer it at the left so it is out of my field of vision.

FWIW

The wiper on my 1931 68B LH drive is a original vacuum outside mount and it parks to the right, (center of the front windshield).

The wiper on my 1931 LH drive 160B is a original vacuum inside mount and it parks to the left.

I think that for vacuum wipers the park position depends on whether it is inside or outside mount.

Can you post the photo. There is a RH and LH triangular plate for the side mount bracket and if they are not installed correctly the tire will not sit in the side mount vertically.
