I welded a tab into the corner of the MT family cage and welded a nut on to it for my harness and repurposed it for the universal 3 point belts I'm now using. I went with the universal belts because you have options for the length of the latch side of the belt, which becomes important when installing a child seat.Bumping an old thread to see if there are any current finds with shoulder belts anyone has been using? Got another little human on the way and would just feel better have a bench with shoulder belts on it.
The seat is secured to the track in three places and the track bolts are rated at 2,000lbs a piece. The seatbelt is anchored to the seat frame.
There is room below the modified MasterCraft 41" seat for tool rolls. I also set the seat frame up with tracks in order to accommodate a future tray build.
