My 84 Daytona has a braided ground strap AND a quick-connect faston to a ground wire.
My 92 Dakota, I believe, has no braided ground strap, but I believe it may have the quick-connect faston to a ground wire.
If the radio mechanically mounts through those diagonal plastic tabs with two screws, there is no ground connection there, so it must have the braided ground strap, or a separate ground wire to the radio chassis, or both.
