I just picked up my new dash board for my Super Minx and it is a beaut. I got it from Dashboard Restorations, Acacia Ridge, Brisbane and Mike is really a nice guy and very good at what he does. He has a fiberglass mould for the Super Minx that is identical to the Humber Vogue dash boards.
His number is 07 3273 5019 and address: Unit 6/4 Lancashire, Acacia Ridge.
cheers, clyde
