Interesting, it did say in the advert that this was the first production Plus Four with hardtop fitted so maybe they started again after the race cars.
The race cars have a Plus Six hardtop sliced up and refettled by the students from Wolverhampton University
You would have thought that the door apertures, windscreen & rear fixings would all be the same with just a 4" strip of material removed from the centre line of the Plus Six roof to make it fit a Plus Four.
Ive not seen any reports anywhere as to how people are getting on with the plus six roof, would be interesting to know if it makes much difference Leak & noise wise.
