Dart muffler configuration

Yeah , they`re offset in/center out and the corners are dented where they would touch the driveshaft. I don`t remember the overall length but I think it`s 22"? You`ll have to check that out. I believe in 68 the muffler inlet was 2.25" and outlets 2.00" and by 69 they had gone to 2.25 in and out.? There`s a member here from Accurate Exhaust (Tom) that can likely show you the way. Great job George, can`t say it enough!
