Sorry, these are the two piece style. Not sure what year they change.
Maybe someone else has something. I'd think a newer Volare or Aspen type might work. Lots in the junkyards.
Unless you're doing a factory restoration consider making a set. They are simple.
I have a friend with a long arm quilting machine who will sew a set for me but it can be done without that.
Here's the set (2 of the 4).
Rear: 9 1/2" wide (outside to outside), 3 1/8" backspace, 3 1/8" center.
Front: 7 3/4" wide, 3 3/8" backspace, 3 1/4" center.
Some mounting rash that can be cleaned up. With a polish they will look great.
