Found some great little bar-end mirrors that are made for bicycles. by taking off the bar-end fitting they fit perfectly and are completely adjustable. They are slightly wide-angle and even though they are very small, they provide a pretty good view because they are close to me.
I should have the tail mounted (after much thinking and revising the mountings hard-points and structure) in a week or two and hopefully on the road next month (crossing fingers and hopefully the snow will not be on the roads

)
Cheers, Jeff
