'57 Traveller wiper unit

[nutmegct]

I'd like to replace the four (severely degraded) rubber spacers/dampers where the wiper unit sits on the mount plate.

Would anyone know what size the bolt heads are, on the underside of that plate? I tried 1/4" as on the wiper unit cover, but no luck.

Thanks.

If I understand the fixings you require, I think you’ll find the threads are 2ba nuts

After much fumbling, I found the nuts on the bolts (the bottom under the mount) are 11/32".

I wonder what causes those rubber dampers to deteriorate so badly. They look "melted".

One of mine was actually like shiny black tar, soft and sticky. Blech.

I used tap washers for my Ser 2 and Minor 1000.

The rubber has 'perished' - like we all will one day
