were to get a head liner for 74 Duster.

I installed one of the ABS ones. I did a little trimming on install like Ross did, it fit fine after that. I did buy one with the tier backed vinyl, which separated as soon as the temperature hit about 90*. I pulled it back out and re-glued the vinyl with 3M adhesive, no problems since.

If I had to do it again I would just buy the ABS liner plain like Ross did and install my own material, since that's basically what I had to do anyway.
