Nope, no metal piece. Sounds like you have a ski pass...or the 'ski pass mod.'
You'll just have the leather flap with velcro, a foam rubber piece, and then the trunk liner (which you could cut out to complete the pass)
Upcoming NYC dates: Jan 8 and 27. See Facebook for other shows and PM me if you can make one...love to see you there!
Mangofy your E46!
