Kinetics’ 1/48th scale F/A-18C is a great kit and comes with a good representation of the SJU17A ejection seat. The kit even provides a photoetch generic seat belt. Eduard ups the ante a ton with its release of a color photoetch steel set of belts specifically designed for the Kinetic seat.
The set has one small colorized steel fret with nine pieces for the shoulder/seat belts and two pieces for the leg restraints. All made with multicolor parts. As you can see in the photo, the kit provides a basic lap belt and shoulder harness.
Addition to the seat is easy. There are four sets of lap belts so those get added first. The seat is pretty flat so they slide right into place. Next, add the adjustment straps on top of the four lap belts. Lastly, bend the shoulder harness to fir and glue in place.
To finish, I added a black wash to the seat and then wiped off. A few dry brushed and a flat coat and its done.
