Rear Shock Bolts

Hey Guys, putting the 69 Dart back together and misplaced the rear upper shock bolts. Can any one tell me what size they are. The new shocks came with the large washers and inner brass insert but I need the rest. Not sure what ... I assume the go in from the trunk. Any help would be great.
They are double ended studs w/a shoulder, the large end goes through the body from the
shock side and is 5/8", w/a flat washer and a torque prevailing nut in the trunk side. Maybe
forgetting what they looked like made them hard to find?:lol:
