Hi all, :-)
Thanks alot for the nice inputs, it for sure appreciated.
bosswrench, with my seat belts the problem is that the webbing is game over, can be seen on the picture I attached of one of the seat belts. And the other seat belt has even worse webbing, unfortunately. So cleaning won't be enough unfortunately. :-/
stevebuchanan, the seat belt on my are not as simple as your on the pushbutton. If only they where, then it would be easier. Mine have the dual retractor setup, so that's also why I doubt I can do it myself, so some experts are probably better. :-)
Besides that, your looks very nice now! :-)
cuvee, Aha, thx, SeatbeltPlanet.com, those sounds very interesting. I'll try to reach out to them. :-) . Only downside is I'm located in Denmark in Europe, this always makes these things more complex and expensive when it has to be send to US. (if only I lived in US!! )
Once again thanks for all the answers.
