Hang on just taken a picture. Not sure if it helps much. Bit out of focus, sorry.
The arched line is the longer one which I thin is both ends and centre of leading edge.
The line it sort of loops through I think is top and bottom of verticals.
that DID help, thanx!
I just want to make sure it's right...
don't want to have to replace the leading edge rods (again!) this soon into the season
