Well, the left hand side (UK passenger side) running boards on my cruiser took down next door neighbours' brick wall effigy - actually, the first clip cracked it (the brick wall, silly!) and the second clip took it down....completely, ending up on next doors drive....the damage to my cruiser? minimal! the running boards were still there, but were lose, so it was removed as it might have posed a hazard to other road users... just a few scrarches that didn't even break through to the metal otherwise. Thing is, the driver side still has them - think I should have these removed too? it would make it mighty difficult to get into...but am thinking, remove this and have just a little step put there instead - would probably look better too.
