have a look.

great pic I may as well replace the seal too.

Yep, sorry about that Don.
It's missing the clip and probably washer both, and the smaller seal goes under the washer with the lip side facing down.
You can get a clip and washer both at an Ace Hardware, and the clip is just a basic E clip.
If I remember, the washer is thinner than a normal washer, (maybe not)
Also expect the seal to be all rubber and not metal clad like the pic d55dave posted.
Either is fine.
