Windscreen wiper wheelbox rubber shaft seal

Hi guys. The rubber seals that fit over the wiper wheebox spindles on my BJ8 have perished and allow water to run down the shaft and drip inside my car so they need replacing. I haven't found any parts supplier that sells these but I have read on the MGA site of someone dismantling the wheel box to remove the shaft to replace it - I don't want to risk that but wondered if anyone else had obtained any rubber seals and just stretched them over the splined head onto the shaft, or achieved a seal some other way? BTW I'm not referring to the flat rubber gasket that fits on the shroud. Richard in UK
 
Got this from AHspares' site; added the red callout. Is that the seal? Not sold separately. They want you to buy the wheelbox.

Looks like you'd have to pull the spline and add your own seal. Maybe some o-rings or pack it with waterproof grease.

Hi Steve, thanks for the reply. That is indeed the part in question but strangely it isn't available separately despite being an item that deteriorates over time and crucial to the fight against water ingress! I suspect that I'm going to have to find some suitably thicker rubber or silicone sheet that I can punch a hole in and slide over the splined end - I really don't want to risk dismantling the shaft and risking damaging it, then having to replace both wheel boxes. Somebody else must have replaced these rubbers at some point - I can't believe that I'm the first!
 
This UK supplier has all kinds of great stuff.

These v-rings look good:

Idea: if they won't stretch over the splines, you could cut with a razor and hold around the shaft with zip tie or wire.

Edit: body copy says they are stretchable.

Please let the Forum know your solution.

O ring that stretches . If you must cut it,
use a diagonal cut so ther is overlap. There is o ring adhesive ( like crazy or super glue ). Heat shrink tubing is also great to work with - large sizes available.
