I'm doing my Firebird inserts in perforated vinyl with the surroinds in grained vinyl. I bought 6 ysrds of perforated and there is no room for error if I make a mistake. I bought 8 yards of grained. Your back seat is larger.

If you make rough measurements of your seat panels. You need to allow for an extra half inch around the perimeter of each piece for sewing. And you need to know which direction the vinyl stretches.

There is a place by me that sells surplus OEM vinyl. I paid $7 per yard.
