I got one. Bought in error as mine's 10 spline. I'll check how many bolts. I'll also weigh it to find out how much it'll cost to post. And, I need to check what I paid fer it as I'd like to get my money back if I can - but as I remember it was cheeeaap..!
I'll get back to you on all of the above when I get a minute - hopefully tomorrow.
