My battery has given up the ghost and I set about sourcing a new one. Ha ha ha easier said than done. Obviously I wanted a battery that would fit nicely into the tray in the boot and allow the metal 'frame' to sit on top of it and hopefully be 'low' enough to fit the retaining clamps. My car was made in 1983 and is one of the first 'trip computer' models. The battery tray measures 255mm x 170mm and I'm looking for a 75ah 650cca battery. Well, its basically impossible - or so I'm told. Any advice greatly received.
