1990 fourtrak pick up


hi all...im a daihatsu virgin...just bought a 1990 fourtrak pickup....which is pukka...needs a bit of tidying, just wondered if anyone knows where to get a set of door cards??? also need some new seats, maybe some buckets ..any advice would be very welcome.
im also trying to source some kit to lift it 2" , ive spoken to dave at bloodredoffroad who was really helpful (definately recomend bloodred if anyone needs some kit,,) and advised that the pick ups have a different rear suspension set up, does anyone have any experience or advice how i can get the rear lifed, dave sugested reversing the shackles but it would mean about a 6" lift which would be to much...any advice would be gratefully accepted..thanks!!
