OK, stretch, i agree: no stops, no good.

the truth is i don't know if either the box or the frame have them. maybe both do. i thought #20 in the illustration for 13b might be the cross member stop, but after looking at the car i think it's a mount point for the skid plate.

since the "1*" marking is unexplained, and original steering box gone, any clues on checking either half for the stops that one of them must have?
