I dont know if his are like mine, which are out of a 300ZX rather than a porsche(and arent nearly as nice as those) but they had those levers on both sides of the seats, which is kinda nice.. Mine also HAD electric adjusters, but people kept moving my seats, so i took out everything for the adjustment on the drivers seat and welded it in place.. Actually shaved probably a good 45lbs..
*EDIT* Nevermind, didnt see where he said that there were two per seat.. *PULLS FOOT OUT OF MOUTH.*
That thing oughta look good when its done..
