I've got Intatrim seats on universal runners but they're quite wobbly. I think this is because they are effectively sitting on the 4 nuts that go through the floor, rather than being flat to the floor, if that makes sense.
What I mean is, after fixing the runners to the seats, I put a bolt through the runner with a nut to tighten it against the runner. Then that bolt goes through the floor to the final nut and washer underneath.
If I don't have that nut, I can't tighten the nut underneath but that nut is, i think, causing the wobble.
Is this normal? Have I got this right or am I doing something wrong?
