i fit and drilled the rear seat hinges. i had previously made these hinges but felt that they did not sit on a true and square line and that that would cause the rear seat to sit at an angle. i made new hinges and located them using the 4-7/8" ref dimension from the floor/bulkhead interface as shown in the drawings. the result is a much straighter pin (hinge) line.
see other post this date for flooring misalignment discussion.
