2nd gen Expy and Navigator, for sure
3rd gen --- maybe, seems like it would but no one is confirming
I'm finishing up a Katzkin install on my 3rd gen, it's DIRT CHEAP if you find an open box sale on ebay or craigslist (seems installers often get the wrong stuff or customers preorder then cancel or something), $200-350 for entire vehicle
However it is a BIG project. Decent upper body strength a must, seats weigh a ****** ton and pulling the leather tight enough to get the clips and zippers aligned can be pretty exerting.
Project WILL take you all weekend with the mandatory frequent breaks (else you'll hurt yourself or screw things up or just sweat all over the damn thing and make a mess).
And you need at least a 12 pack of beer.
