I'm looking to rebadge my xB as a Toyota bB and while that's cake for the outside, does anyone have any info/ideas for removing/covering the Scion emblem embedded in the center of the steering wheel? or better yet, replacing it with a Toyota emblem (if that's even possible) ?

try using the search...I had a topic on this already.
