You can get the logo pre spaced out from FCP/Volvo ect. Double adhesive kit to stick it on, then pull off the temp holder. I used masking tape, a level and a ruler to center it horizontally and vertically. If you follow that route, the last O will need a little piece of extra 3M adhesive trim tape to anchor it. Otherwise its not very well stuck on and could be knocked off in a carwash. Use a good adhesive prep for removing wax as well.
I went for a new logo since my VOLVO letters were in medicore shape and i was moving the S70 and upgrading the T5 badges at the same time.
