trunk spring adjustment for trunk with wing?

You will add spring tension by dropping the tension rods down to lower holes . The only danger is the dam trunk will drop when you go to move to a different tension locations and the trunk is very very heavy!!. Do yourself a favor and take a picture with your phone of the springs and how they're set up in case they come down and you need to put them back into place and that's very complicated remembering of positioning. Removing them completely and then reinstalling them can get very complicated because I believe they are left and right sides. I would go the furthest tension location as mine are set on the second to last and very firm with out a wing.

Good luck
