As far as I know, the only difference between the springs in the later years is the length. Also, the perches are in a different location on the axel, but other than that, I thought they were basically the same. Ya might post this question in the garage on CK5.com or on Pirate4x4.com. Also try calling a 4x4 shop. The manufacture probably can't recommend putting it on a vehicle that it isn't spec'd for, but the shops would probably know if it will work and would be more willing to tell you (especially if you make it sound like you might have them install it.)
