Actually, I paid $163 for new black window trim pieces at the dealer. Took me about 1.5 hours total to remove the 4 chrome pieces and install the new black ones (once you do the first one and see how it goes, the next 3 go much faster). Sold the chrome pieces on this forum for $80. My net cost $83 and I have OEM pieces on my truck.
Plastidip might be a little cheaper, but will probably take longer than just replacing them. I think OEM pieces look better IMO.
