Hi there,
Firstly welcome from down-under.
If you drop me a PM with your email I can send you the part's book for the "modern" trads.
As to a Haynes typle manual there's no such book for the Morgan. Best solution is the parts manual and a Haynes manual for a car with the same engine (Ford something or other); all blended with help and experience on this site.
Hope this helps,
R.
