i'm thinking using the rear seatbelts for the rear passengers.
did anyone made a project like that?

very first thing I did was install rear seatbelts holes were already there, bought a kit and installed

After I installed the EZ Cool on the floor and rear bulkhead, I did the same as Jay: ordered a kit and installed them in the existing hard points. I bought longer than normal sets, since I will be securing guitars and golf clubs back there in lieu of people. Looks/works good so far.
