Looking for special pressed bolts

I'm looking for a set of new pressed bolts that attach the front of the
leaf spring hanger to the frame of a 68 dart, they look like stud Bolts for a wheel rim except they only take a 3/8 nut it is 1 1/2 inches long. If anyone knows where I can get these on line it would be appreciated.
