looked at a 73 Dart today

Car looks real good ! All original 1 Owner !
got a couple of concerns though hopefully someone can answer a couple of questions.
Below the doors there is a ridge where the rear quarter panel overlaps the rockers ? Did chrysler eliminate the lead on the seams in 73 ? Or did somebody at the factory goof ?At first I thought maybe it was a poor repair but it's the same on both sides .I know my 72' has lead there to smooth the seam.
Also would a 73' with front Drum brakes have the same upper a-arms as a car with discs =( large ball joint ) ?
Any help/comments appreciated ,Thanks !
