They look crooked because the idiot engineers that made these leave no space to center them. I couldn't even get the entire strip of tape on the tips to attach to the flat surface of the plastic sills, I had to sacrifice a little bit of hold on each side. Whoever made them should get shot in the face for making them so small, idiots! But I made them work and am happy with the result, my only wish is I would have liked bigger stainless steel sills.
I will get a tape measure on them and throw up some pics so you can all see whether I did a good or bad job ha ha
If you can't wear it out, burn it off
