I have a used AEV spare tire carrier for sale. It has all the bits needed to install on an AEV rear bumper. It came off a 2010 JKUR. As shown in the photos included in the sale is the carrier and the tire mounting plate. The through bolt needed to mount to the bumper is present.
I am in N Boulder and can be reached via cell SixOneTwo 816 7853 or email at pgopinath AT comcast DOT net.
Thanks for your interest.
