To determine whether your LXi uses the 1R11-066, 151, or 152, from what I can tell they all share the same bellows and piston with the only difference being the number and position of the holes in the top and bottom plates. I've gathered this info on top and bottom plate hole/stud count:

1R11-066:
top Plate: 3 hole/studs
bottom plate: 3 hole/studs

1R11-151:
top plate: 2 hole/studs
bottom plate 2 hole/studs

1R11-152:
top plate: 2 hole/studs
bottom plate: 3 hole/studs

You should be able to do a visual inspection of your bus's air-spring top and bottom mounts to determine which spring is used for each axle. My LXi definitely has the 1R11-151 on the steer and the 1R11-152 on the drive.
