hmmm........I don't think they are.
My back seat is long gone so I can't look either, but I just took these pics yesterday of a '99 Ebony ....I think the front's look more rounded on top, and have a seam down the edge, I can't see that in the rear ones. Plus the fronts are leather and the backs pleather I assume, same as the covering. The headrests looks just as shiny as the rear seats....not leather.
The rods/poles may be the same though???
