Scott,I got a horse blanket style cover from LMC although mine is for an AD truck.
I ordered it as a cheap alternative to allow me to use mine before I dropped the big $$ on a proper bespoke upholstered seat.
It appears to be more of a cover,rather than a replacement for the original.
It took a bit of wrestling to get it on as it's one piece but it'll do for now,i've since trimmed it around the retaining tabs on top of the backrest.
Might be worth checking out.
Here's how
mine turned out.
