The old wedge does look the same as the new one. The new stem looks like the the old one, except it's longer and a different colour.
When I put the longer stem in, wriggled it around (i'm talking 360 degrees) and yanked it out again, there were no scratches or anything on the new stem.
I'll leave it the way it is at the moment. I think it's going to be a great talking point when I meet new people.
