Ranger 750. P11 and P11A both have seats with the front mount that lies on the frame backbone under the fuel tank. P11 frame has two pegs at the rear of the frame to mount the single seat. P11 A rear seat mount uses two studs that mount in holes in the fender mount (which is brazed on the rear loop on P11A and Ranger 750, not the frame). Ranger 750 mounts to the front with the peg on the frame and the rear with the funky bracket that attaches to the upper shock bolts. The Ranger 750 rear fender loop does not have the two holes in the rear fender front mounting strap like the P11A.
