Ah yes... Forgot the manufacture that does
I wanted to do this mod on my Tj.
Only problem --at the time--was no place for the tire.
A member on one of these jeeps forums had this brilliant idea. He used the factory hinges to make a swing away tire carrier.
The manufacturer was soon to incorporate the tire holder In the kit.
Not sure if they did so.
Maybe someone will know the name or if I remember-I'll post
