Dear Tim, Thanks a lot for your guidance...very useful. Do you have any preference for the type of ball, I think it's probably down to the look of it in the end,unless the swanneck has advantages, such as clearance,over the flange??? type.Do you know the part no. for your bar by any chance? Cheers, Steve S. Dear Latrine, Let me you know which route you decide on. I think you'll be ahead of me on this one as I have'nt taken delivery of mine yet,but there's no harm in forward planning! S.
