Yup mine was done by the Car Hood Warehouse in Chessington Surrey. Excellent job as it was fitted for the previous owner in 2010 & the rear window started to come apart last year. The CHW did it under the lifetime warranty with no questions asked. Damned good service.
It is worth asking around the trimmers in your area, some will redo windows, but unless it is 100% then it may not be worthwhile as the window is around £230 or so. A new hood for a 986 is £650ish or was when mine was done.
Yup just checked it is still the same price.
