Is it worth a little read through on the "Which Wheels" section of this excellent aid to us all
gomog Good luck.
Tried that - but unfortunately couldn't find anything useful.
Maybe a member of the MSCC could help, I'm not otherwise I'd enquire for you.
I guess they must have some kind of technical reference manuals somewhere.
Failing that give Keith a call at BHM there's not much he doesn't know about most Morgan's and he is most helpful.
