Chris,
May I suggest that, if you haven't already, you visit Krazy Horse in Bury.
They are a great bunch of chaps and I'm sure they will be able to put your mind at rest. They are also very clued up on S&S things.
As for your comments about Morgans quality in general, you will get a very balanced argument from every one on this forum.
Yes, they can be a pain at times but they are hand built cars which reward a caring owner and I think all will agree that the caring, fettling and just down right messing about with them is one of the many pleasures.
With the greatest respect, if you don't subscribe to this theory then you may be well advised to put your hard earned into something else and save the pain.
Re. Caterhams, a couple of people I know have them and they are no better or worse than a Morgan and IMHO no where as nice.
I hope you find what you are looking for.
