found some seats today on ebay, saas buckets, they were just around the corner from my house and the fit perfect, like the were made for a z. the rails bolted straight on to the seat, i just had to drill two holes on the seat mount on the floor, just to shift them in 8mm, thats all !!!! . i know there not originals but they were cheap and are in perfect condition, and i think the look and feel great!
About the carpets-
got them from auto barn
ill get some better pick when the interior is finished :-)
