73 duster abs headliner

Do you know if the 1973 ABS headliner will fit the 1970 Duster?

Yes, but the sail panels are different. The '73+ cars have a plastic side panel that goes all the way back to the rear glass, the '70-'72 panels don't cover that far back and there's a cardboard panel that gets covered by the fabric of the headliner. So, you'd have to figure out how to make up the gap between your sail panels and the headliner, the ABS headliner ends just below the later sail panel

Not my picture, I borrowed it from @zkx14. Red line shows about where the '70-'72 panels end, black line shows where the ABS (and original cardboard) headliner ends.
