dont think of it as a renix seat... as its really not. EARLY model seats, go up to like 96ish...
i modified a late model xj seat to fit on my 1990 xj, with minor welding and fab work, can provide pics. GREAT seats... the early stuff is TERRIBLE, especially the ones with the hard plastic head rest... wtf were they thinking?
but no, the later xj floorpan is differant, making the sliders differant.
