With the rest of the new chrome in place, the gas cap that I thought looked okay was no longer satisfactory. Sunbeam Specialties sells a new chrome cover, which includes the push button release and new hinge pins.
The cork seal was okay, but the spring loaded sealing assembly had to be fitted to the cap, requiring drilling and fitting the four small phillips screws on the right.
The shape of the hook on the pushbutton required fine tuning with a small file to get it to latch.
The final fitting left the cap touching the paint work when open, which I resolved with extra gasket material where the cap mounts to the body.
