depends on the age of the caddy, on the later ones the front slider handle swapped sides. the early ones have MK1 golf seats, later ones have mk2 seats. only difference is as above, handle swapped sides./ so you can swap n change MK1/MK2 seats, just if you get the wrong combo the slider handle wont work. either flip seats upside down and swap the handles, or just manually pull the locking pin with your finger to move the seats
