Yep, I'd agree with Big on that, what the heck, ya already spent the buck and a quarter on it so stick it on the inside of the GB door. And while your at it stick one of those tire pressure sticker in there to. It breaks up the monotomy when ya go lookin for a map and I doubt of anyone but you is ever gonna look inside the box anyway.
Your real problem is gonna be trying to fit one of those chincy cardboard glovebox liners into the hole. Good luck there.
