Will these lugnuts fit my dart?

Well I feel dumb now. I should have checked my lugnuts before I posted. Well most of all my are super rusty open end lugnuts but I just remembered I had like 3 mismatched chrome acorn style lugs on the car. I pulled one off and looked and it. The nut had "7/16-20" stamped on the side. I check it with both sides of the car to make sure they are all the same and they were.
Thanks for the help guys!
