1970 Dart Swinger 340 bumpers slotted or not?

What's the story on what are the correct style bumpers for a 1970 Swinger 340. Slotted or not. I see Scamps with slotted bumpers but not Swingers. My 70 Dart Swinger has slotted bumpers front and rear. the rear looks to be a rechrome and the front is an original in decent driver condition. They will both be replaced when the car gets refurbished. Are the AMD replacement bumpers any good?
