WHwest8597 85 #1 Posted June 19, 2022 I have 2 1996 314-8 and 2 315-8. The seats have 5 3/4 wide and 7 7/8 long bolt patterns. Northern Tool 135001BK seat has 6 wide and 5 long bolt patterns. I have read this fit 416-8 models. Can someone post a picture of your seat frame and the width and length of the slots on the frame from the center of the slot when measuring width.
