Its an 'tension spring' meanings its pulling the two spring mount points together, and I can't see how i am going to get it anywhere near the ideal. Right now the lever on the arm is sitting off the actual hex head bolt that restricts movement. Any help would be appreciated. I am running an extension bracket due to the 3" nominal lift in the back, should this be removed - if I do remove it the spring will come under more load and try to shorten its length.
Phil, check out page 48-51 of Y61 Patrol Reference document, should help out.

After correction the spring is closer to a 90 degree angle (full line)
As opposed to where it was prior to the bracket being fitted (dashed line)
