I have the same thing on my truck. Though I totally forgot about the other hole. Right now I have them at the bottom hole, which is the highest. Didn't realize I could move them up and put the stock shackles on and get the 1/4 to 1/2 inch higher in the back that I need. I guess I need to set some time aside for that. BTW you can see how far the spring change is from this pic
