Hi Gents
Just an update, to let any one intersted know how I have decided to complete this issues on my car.
I have decided to fit what I beleive to be a Worsley Hornet Part
Part Number 39948L
ie its a Mini Mk11 part with a chrome end cap.
it looks correct to me
but will keep my eyes open for any thing better or if I manage to find any more origianl info...
thanks for everyones input.
Steve
