G'day Norm,
Sorry, meant to reply earlier but needed to look at the Anniversary in the shed first as I've never done a belt change on one of these before. Unfortunately there is not enough of the drive tensioner left for me to look at in order to help with your question.
I notice there is an owners manual for the Evolution in the manuals section and it seems to be a similar setup (?).
Sorry I can't be more help.
Cheers,
