Just so you'll know. While the seat bottoms are the same structurally between all the wagons, there are differences.
You have a Roadmaster so it's vinyl. There was a cloth third seat but only in Custom Cruisers with cloth interiors.
Most importantly, the tan interiors are not all the same color. The shade of tan changed three times at least (might be four) during the six years of production.
I believe you have a 96 right? So be sure to get parts at least from an LT1 (94-6) wagon. Someone else can chime in here but I THINK there was a slight shade change somewhere during the LT1 productions as well.
Color changes apply to the cargo cover too.
91 and a few 92's had a VERY light cream color
92 and 3 had a dark "butterscotch" tan
94 through 96 had a medium tan with possibly slight shade change somewhere in there
Just to make sure what you get is the right color.
