rear suspension rebuild

Hi,
I've just had the shock rebuilt and am having a go at the re-assemble. . .
I have nearly finished but am unsure of the procedure for tightening the rear-most bolt which attaches to the swingarm. .
anyone had a go at this ?, I'm having trouble getting it to tighten centrally. . .
