After a little hiatus, (and over fifty other models started and finished...) I'm back on this.
I made the harness for the driver's seat. A couple different kinds of tape, some hand cut Mylar and some custom made decals.
They are Schroth ASM (Anti-Submarining) so there is an electronic inertia reel that mounts into the back seat. I just took off the Momo pads on the real car, but since they were on it for 20-some years I thought I'd put them on the model.
