I'm with you on that Ian, except I don't have any paperwork for mine.
I have spoken with dvla and they gave me forms to fill in, and said that they would need some kind of verification from a/the club ref year of manufacture etc.
Have spoken with John Hearn about this and he's more that happy to help.
the quest for a starter motor continues, the one bought from German Ebay is wrong--it's for a junior.
The one I (think!!) need is EJD 1,8/12 L57 this is what Crispin has on his and it looks right for me.
I will actually need 2 as Dave Hilton's new toy doesn't have one either.
cheers
Ian
