When you break down the change over it isn't real complicated, you need to preserve the proper seat height with operator off the seat and you need to preserve the rear most seat position in order to engage the rear position seat lock.
When swapping out the seat platforms from spring to air ride if the new platform is too low then you can shim it with washers to raise it up. If the new platform is too high but within an inch you could push down on it to get it to latch in the rear position.
Setting the seat up to latch properly in the rearward position is easy to do, flip the seat to the rearward position and latch it in place. Make sure the platform is in the rear most position, then mark the seat mounting to attach to the platform.
Just a guess but I would think the seat platforms are very close in height and should be easy to swap out. If you have a lot of back problems this might be a real help for you. Well worth the money imo. A little measuring and research on your part and you should be able to get a good idea what will work.
