Thought I'd go ahead and comment so this thread comes up on the board for all to see.
I'm doing my brand new inner and outer wheel wells, and this thread sums it up. They dont fit. I placed a huge order 2 years ago to combine shipping costs and.. (wow- I'm 2 1/2 years deep into this airstream I was just going to "clean up and go camping". Ha)
So needless to say... I wish I had kept my old interior wheel well covers. Maybe someone else will catch this before they order waaaay ahead of time, and throw out their old!
