Towards the end of S1 production we did see some with the more standard 5 stud wheels which went onto the S2 so I am guessing they can be swapped if you ever get into really difficulty.
Finding someone to cashflow 100 wheels is pretty serious.
Is there any way that they would accept less but a higher per unit cost so they still see profit overall, not wanting to give them carte blanche but...

Everyone loves a Morgan. Even me, unless it's broken again.
