Rover P6 Club

I have just received a clutch master kit I ordered in a plastic bag rather than a manufacturers box. It has two seals and the convoluted boot. Only one of the seals has a hole through the centre yet to me they both need to be holed. One to slip over the piston and one to push on the end which is held in place by a plastic clip which the return spring pushes over. Am I missing something or have I been sent the wrong parts.

Thanks
