E89 Seat belt removal

[PanZEr89]

I’ve been looking at the possibility of changing the seatbelts in the car either to a coloured option or more likely the black with M-Sport stitching option as I think it would compliment the black interior.
The sites I’ve looked at require me to send my existing belts for upgrade but of course this means I need to remove them and although I’m aware of the fastening to the seat I can’t find any reference to the upper fixings.
Please can anybody help me find a “how-to” or share experience/knowledge on the process.
Any pictures of belt option you’ve done would also be greatly appreciated.
Cheers, Ian

If anyone has used one of the companies that offer the service I’d appreciate their feedback on service and quality of the re webbing.
