Roger,
be careful if you have the battery tray in the back behind the seats. The tray has no floor so you need a battery of those dimensions or make up a floor for the tray.
The AA fitted a type 075 to my Roadster last week.
Why not as Uncle Melvyn (Melvin Rutters) or another dealer to quote so you get the spec.
Some people fit Odssey batteries. I have always gone for standard gel batteries & used a CTEK charger to ensure long life.
