Order new leather seat covers
Install them your self
Not that hard. Tedious yes but not hard.
Just replaced my cloth seats with leather myself.
ETA, just looked and they don't offer new seats for your ride OP
However, if you do find some it's not that hard to install them yourself. All you need is some wrenches / sockets, a pair of hog ring pliers and some hog rings.
