Update:
Ordered the brake bleeding spanner 10mm one end and 11mm the other, it arrived, had all the necessary kit ready to go.
Took the wheels off, cleaned the areas and here we go. Rear drums 6mm nipple, front calipers 11mm nipple the moral of this story is that you never have a dulll day with a Morgan.
Job done and all is well so a good end to a good day.....
