No problem with taking a look. I've done complete restorations on other British cars so this shouldn't be a challenge. It appears as if there are few if any repair manuals for these cars so I guess that I will have to wing it or hope that this forum can provide the answers.
You could also try Terry Foxen at GEE in Nailsworth, he keeps an eye out for parts that will fit older Morgans (my dip switch died on the '76 car I used to own and Terry had just the right Lucas part available).
For a 1970 car search Amazon / other booksellers for: "Morgan Four Owners Workshop Manual", Brooklands Books OWM796, ISBN 1 870642 635 (that's the old ISBN before a renumbering systems).
Cheers,
