Volvo Emblems

Ok, so I've got a 2000 S80, and I have gold emblems on the back. I want to get silver ones, so to do this where should I get them? Would the volvo dealership near me be the best chance to get them? Or where else? My volvo mechanic? Thanks for the help. And would Volvo care if I put the T6 logo on my car even though it's a 2.9?
