My coworker has this bike carrier for sale and is designed for vehicles like ours with spare tire carriers on the rear gate. It's for sale at $80 (normally goes for $189). He's selling it, as he no longer has the vehicle. PM me with a phone number/email address, and I'll pass it along. This is here in Houston.
