G'day Russel.
Are you doing an A7 or A10 and what year?
Under Greybeard's avatar you will see a little envelope. Clicking that gives you an email page.
I know pictures aren't as good as a close up touchy feely but there are hundreds of pics on the net. Not all are correct but you can ask here. Click the "Musky's Plunger A7" link at the bottom of this post. Not correct with a 57 A7SS top end.
Cheers
