I just added GOWESTY seltbelts to the back of mine, 3-Point, the kit is a
bit pricy but is a very good kit, start with the passenger side first to
get a feel for installation, then start with the drivers, i had to trim
the cabinet, in the back with the shelf, so I could spin the seatbelt into
the factory bolt hole, I also got extra trim pieces for the closet, where
the belt goes through to trim out the inside of the linen closet too. The
picture of the setup on GOWESTY is worth a 1000 words....
