ok so i recently got my Z back and i notice the hard plastic that goes under the Z mat in the trunk is missing. its the hard plastic that goes ontop of your spair but under the mat. what is this called and where can i order it

 

You can order one from any dealer or contact Courtesy Nissan.I'd think it
would be called a "spare tire cover".Its actually a piece of a corrugated
material much like carboard,with a plastic coated cover.Its much like
Corroplast that you can find at most hobby stores.Its used for poster
board.If it were me,I'd just make one out of that material.There is also a
small block of a foam material in the center for support over the spare.
You don't see the piece.Its covered by the mat.A dealer will prolly
charge 100 bucks for this part.You could easily make one for $10 or less.

 

yea i had the foam but my brother threw it away i have no idea why but when i cleaned my car he tossed it out. but sounds good thank you for the response
