Just heard from my dealer. The resolution, for those of us who have US-bound orders already placed expecting the "traditional" configuration, Morgan will provide the brackets at no charge to allow the dealer to make the change back if the customer wants, at no charge.
For any new orders, there will be a charge for the parts and dealer labor.
This confirms one very important thing - the change is in fact easily reversed if desired! And it's good to hear that if you have an order in expecting it to be one way, you can still get it looking that way.
