My rear seat covers are torn and I’m currently looking for a replacement that matches, but it seems like they are extremely hard to find.
This is what I’m looking for.

Try these guys for your parts, try to be as accurate as you can with your requirements, I’ve had very good luck with them others that I have sent there have also. The best thing is your yard near you could end up having what you need. good luck

 

And if what Iowan says does not work out.... Stop by your local Upholstery Shop, they should be able to fix you rite up... Cheers
