I have heard back again from Morgan. My pedal box does need the support bracket for the brake pedal. Morgan say that this mod should be within the capabilities of any competent garage. I have contacted a couple of the local air-cooled Porsche specialist garages but have heard nothing back from them. Normally I would have chased them up during the past week but spent the whole week sorting out the consequences of a burglary at my French house on Monday night, where I was either gassed or drugged (ketamine spray) and was quite ill afterwards for a couple of days.
