if the pan is not badly damaged, they can be repaired fairly easily.
Attached are two photos of how we patch up the front corners of the seats. sometimes we add some more plastic. The plastic parts can be glued together with PVC pipe solvent cement. It won't work in the 82, but for the earlier years, in the back, instead of fixing the corners of the pans we drill holes through the hinges for the glove box door. I have a picture of that too, but am having trouble finding it.
