OK, didn't get them as cheap as $159 but didn't get them as high as $389 either.
I can't exactly remember the price but it is in the $300 range. I don't have time to bring the car in for the install yet unfortunately, but I'll take pictures when all the items are in.
Many things I'm asked to show people in the Crossfire cannot be seen while the car is in motion and doors closed, so I'll get to show the sill plates.
And I have plans for the original sill plates.
