1992 ranger rough country lift question

[Csd4682]

So I have a 92 ranger 4x4 and I'm looking at getting the 4" rough country lift. The lift comes with 3 inch blocks for the rear. I measured the stock blocks that are already on the truck and the factory blocks are 3". I read rough country's instructions and the way I'm reading it, it seems like they want you to remove existing blocks and put theirs in. obviously this would not provide any lift for the rear. Would like to get feedback from people who have this kit. Maybe I'm missing something or not reading it properly. Thanks for any input.

I know on my SuperLift kit (4") it came with lift blocks. I had to "stack" the 2 blocks to get the desired lift (the stock one had the bump stops). This is not the best set up. It works, but isnt the safest route. I ran a set of Duff traction bars to help with the axle wrap until I bought new lift springs (SkyJackers). Some people have had the blocks come out, I would seriously look at some new springs when the funds become available.
