Thanks @jcreviston . It is a large Hightower set up mullet but the rack can fit full 29er. The front tire carrier/bar never comes close to hitting the spoiler but could if you really extended it. As for the front tire, I marked the glide bar so I know the correct spot for the tire carrier to be...
Was hoping my Hightower would fit but it’s nowhere close to 70”. Looks like the kuat trio roof top rack is a good option but requires removal of the front wheel
