Heres another picture of my wheels before I mounted em up..
I'm thinking I could attach something from the backside from those other holes that "look like" universal bolt pattern style (those holes are there to shed weight)
1 or two studs comming out from that position could work..
I could use some a coupler nut or something like that then drill 2 small holes through the pizza pan to attach like that possibly?
I have 16" wheels.. if I could find some 15.5" dia pans, that would sit right inside of the lip causing a flush effect..
I figure any little bit will help and it can't hurt..
That and I love salt flat moon style disks..
