Just youtube headlining replacement videos. Basically you have to pull out the whole roof panel out, remove the old fabric, get rid off the old foam and glue, recoat with new foam and glue and new material. Then stick the panel back in. That is the proper way to fix it. Honestly not worth the hassle doing it yourself, just take it to a upholstery place and they can sort you out for pretty cheap (got mine done for 250aud in australia) as they have the expertise and tools to do it most efficently. Doing it yourself first time can take the whole day and can be very fustrating!
