Nail it down with a "Smallest" Head Brass Brad... Take the door off the bracket & Drill a "small" hole in the center of the Badge through the fuel cover (1/8" thick) ~ stick the Brad in the hole and bend it over on the backside, and it will never fall off with a solid brass connection pinning it down along with the GOO they put on the Badge... We really can't call that Goo Glue can WE...!!! Oh, this fix works every time without fail, thats more than Smart can say...!!!
Oh, do you see the Lineage of the Genes...
