From right to left I'd say wheel nuts, d##n lockwashers, buggered up wheel studs, dunno, and that tapered cone I've seen somewhere before but can't remember.......Mike
Wheel nuts would be painted yellow,buggered studs aren't wheel studs but maybe engine block studs & nuts/LW for studs What dia & length are the studs???? . I wonder if tapered cone is crankshaft spacer(key 11)?
I have looked on the JD parts site but I will look again today. I found out the studs go in the top of the cylinder head for the intake and coolant pipe. the machine shop removed them I guess they just used vice grips, I shoulda took them out myself. I put some pictures in of measurements of the spacer and this small pipe.
