I order the door sills last week and fixed them myself you can get the back sills cost was £16.12, front sills was £26.01, parts man didn't say you could not buy back only. I have not got wing mirror covers on my car very easy to fix sills in place five mins ,I think the front look great the back are not as big as I thought they would be about 10" length think they finish door off quite nice .
