From the parts book for last 4 seater Roadster and Plus 4's built, with the last in 2017 I believe, differing parts for the following items:
Chassis and floor boards front and rear
Wooden frame and skin
Doors and sidescreens
Hood and frame
Fuel tank and mounting board
Bonnet each side
Rear and quarter panels
Rear leaf springs
Rear seats, mount and belts
Spare wheel carrier
Rear number plate panel and mount
Rear lamp plinths
Internal panels
Carpets
Strangely no mention of a taller screen. Not sure how all this detail impacts a 60's car, but food for thought.
