Will these lugnuts fit my dart?

Porksoda;
The answer to your question is maybe. Your vehicle when new should have had 10 right hand thread 7/16 x 20 and 10 left hand thread 7/16 X 20.
If you have not changed any of the studs that is what you will need. As far as the lug nuts you posted starting from the top #1, #2 and #5 will fit steel wheels and aluminum wheels with a tapered seat. Lugs 3,4 and 6 are for different thickness mag wheels and use washers.
The wheels that you showed appear to have a tapered seat and would use lug nuts #1,#3 or #5.
The next issue is the size lug nut #1 will use a 3/4 inch socket and lug nuts 2 and 5 will use a 13/16 in socket. It will have no effect on the steel wheels but you will need to be sure that the socket and lug nut will fit into the recessed holes on the aftermarket wheels.
Hope that helps.

If you have factory studs NONE of the ones shown will fit your car!!
