Having now received my copy of this super issue, may I add my thanks to Digby and his authors?
In case anyone else recognises my car as the one with added foot space at the top of page 29 I should, in fairness to Peter Down, mention that this arrangement is shown in one of his wonderful drawings available to all in the document downloads. Go to technical downloads/interior/drawing of PA floorboards where he also shows the passenger side one. All I did was copy it!
