base options
 

Should my base z have cone with 2 rear bars in the hatch area or just 1?

If you are referring to the silver bar and trunk cover the base doesn't come with the trunk cover.

Yeah I drove one that wasn't the base and noticed 2 bars then I drove mine home and it just had the one. I didn't know it was a trunk cover

You have the holes for mounting the trunk cover, you just don't have the cover. It's pretty pricey, but if you can find someone that doesn't want theirs, you can get a deal. I bought one for a VERY good deal.
