& why does it affect some cars, but not others?
Is it the wheel position that's different, or is the body positioned differently on the chassis?
[Looking at my S5, which has offset wheels, there's a slight gap between the leading edge of the wheelarch & trailing edge of the front wing. Perhaps the arch could be moved forwards.]
If it's the wheel/suspension position on the chassis, it will affect handling. I wonder whether 'forward' or 'centred' position is correct?

I would be very surprised if it was anything at all to do with the chassis and suspension. The chassis will be made on a jig and will be accurate to fine tolerances.m Is it even made by Morgan or someone else anyway?
The bodies are hand made / assembled and that means variation from car to car. My guess is that its an issue of the positioning of the rear wings or possible of variation in their shape and the position of the curve of the arch.
Its not good. If you had an RTA and your car came back from the repairers with wheels not central in the arches you would reject the repair
