it's plastic going on metal, does it really matter? If you want an exact fit rap the outer threads of the of the s10 lug nuts in one (1) layer of thin tin foil, spread some epoxy on the foil and screw the plastic caps on.
The foil will keep the epoxy from sticking to the metal threads put will adhere to the plastic cap. Tada!!! instant screw on fit.
oh and make sure you let it dry for a day as one piece (lug nut + foil + epoxy + plastic cap)
