Re: EF seats into ED
ef and el have a bracker welded over the original design floor pan. So I guess you could get a spot weld drill and get tat bracket out of a wrecked car and weld it in. Shouldnt be any problems then. Unsure if you can change the seat rails. It certinally would be easier that way. Talk to steven i think he's welding the bracket in to his car.
The ed's have the same floor pan as ea and eb anyway.
