Job done!!
I did get it to work yesterday, by using a 30mm socket over the top of the plunger and tapping it hard with a hammer, I did this because the copper ring was bending up the way ( just a touch) and by tapping it back down it made a better contact....I think
The new contacts and plunger arrived today (special delivery) and were fitted. The parts were sourced from AUTO ELECTRICAL SUPPLIES (SOUTHAMPTON) LTD, tel 02380211988
they were very helpfull and knew straight away what I was after. Total cost was £24.68 next day delivery, which it was

( unusual for the Highlands)
One thing I would say though, is not to use the split ring washer on the input contact, as theres not enough thread for all the fittings. There were not split ring washers with the old contacts anyway.
Does anyone know if the old contact would of came with the recess in the horse shoe shaped part to accept the plunger, as the news ones are level?
Also am I havering when I am saying that it is starting quicker than before?
