To the OP if you are interested PM me, I have a full set of the old Performance Products vinyl seat covers in the tan and brown two tone pattern. I kept them when I wrecked my 00 but I now have an 02 w/ the grey interior and don't see myself ever using them. They are in real good shape I used them for a year or so before I bought a full limited interior for the 00, they have been in the attic since. There is a small tear on the drivers side where you slip in and out as my seats were base and these are for the SR5, thus there was less bolstering in mine, I never take passengers so the right and rears are perfect. They even come with a cut out for the manual lumbar and covers for all headrests and pouches behind the seats. They fit very well with zippers and velcro and once in look stock, I had people ask where I got the leather. If interested I'll bring them down and snap a few pictures.
IIRC they were around $400 brand new, but make me a decent offer and I'm sure I'd let them go.
