Could someone with above book please confirm that the brake piston/cyl. assembly part numbers are 10548 as on the box labels. The parts look like the exploded view in the service manual, but it would be nice to confirm the part numbers. These bolt-on cylinders look like the cylinders on an early E except about twice the size, so they must belong to the 420G I had years ago. Other info is DEC70, PIST CYL,QTY.1,10548, Jaguar Daimler parts.
