1973-1976 A-Body door parts needed

I have a pair from a 74 Duster but one is cracked in half & as MoparMike1974 said, the attaching tabs are almost always broken (50 years of decay & abuse) & the window felts on the inside are not reproduced by anyone any more, I checked into it, also the felts are attached to the plastic door trim pieces & not easy to remove without bending them. DMT makes replacement ones, but you must figure out how to attach them.
