I was surprised at how well this Poly Urethane piece fits the car. None of the fussing with sanding and shaping that you expect with parts that are made of fiber-glass.
If you intend to install this with the provided double-sided tape this is a ten minute job.
I elected to make a sturdier installation by using nuts, bolts and rectangular flat washers in case I get careless and hit a curb.
All-in-all, a first rate piece.
