Regarding mudguard widths: don't forget that the Morgan is still, to a large degree, made by hand. Even if all the mudguards arrive at the factory pre-formed they are cut to fit the car by hand. Almost invariably the width of the mudguards will vary from side to side and very likely now two cars have exactly the same width guards even if the specifications for the wheels are the same. It may seem ridiculous but someone I know asked for a tape measure specifically to show that the width of the rear guards varied from side to side and they had trouble finding one.
