Mine were on the car when she ensnared me.
I have"tightened" them up as they were not brilliant at keeping the door open on slight slopes.
Now better and no shin bumping except on quite steep slopes.
I don't notice them now, my 4/4 had leather straps and as it was a 1992 I was reluctant to " modify " fitting them due to the lack of mounting places and resorting to woods crews/ mounting plate etc.
I am keeping an eye on the drivers door hinges though as there are signs of slight wear. It's ok at moment so no work needed yet.
Maybe a job for the winter.
