[Staowners] Wiper motor repair - mounting plate source

[Richard Atkinson]

Hello,

 From your description you've got the Mk1 wiper system.  The mounting  
on this was shared with several other cars of the period, including I  
think the series 1 Land Rover.  Anyway, you can buy the 3-point rubber  
mounting plate for £12.50 + p&p from these guys:

Hope this helps,

Richard Atkinson
