I would take a look at the armrest in the 2001 Buick Lesabre. I have the complete seat but I would think the arm rest could be adapted. It is a fold down. Other GM cars of the same era have the arm rest. It would mean cutting the seat back and making a frame around the hole to reweld the seat back springs to.
A sample but there are others.
