Probably showing my naivety here and/or hopefulness, but is it possible to source interior trim as shown in the photo's. Do you have to find second hand stuff from a wrecker? or is someone somewhere making reproductions?
If thats your worst door trim, the material still looks good.
I would carefully remove it from the old backing board,
Give it a good scrub clean, and fit it to a new backing board.
I reckon, when pulled flat & tight on a new board,
you would be very happy with the results.
Both the rear door trims are of good condition.
The green material is generally good throughout, but
the grey shown in the above photos has had a patch
placed on it around the door handle on both front trims.
The patches are only small but still conflict with where
I won't to get to with the old gal.
