Custom TB number in Trackables Posted October 25, 2010 No. And who would know that your normally issued plate number is a TB? Your state charges 40 bucks every year for a vanity plate? Yikes. Forget the plate and go for a sticker/magnet/decal with the TB image. Maybe you'll top the average of one Discover log per year. Edit: spelling My plan eas to place a small TB decal between the numbers on the plate. They are grouped like "433 GFE" so the TB decal could just go right in between. It could however be easily overlooked. I might just go with a regular decal and get "JEEP 4 2"
