I am getting a body lift in a week or so and ther are ST's here that have made a bracket or something to get it back on. I am planning on making some blocks out of metal stock to bolt it back but I have a sop that I will be working in wheN I get home.
to put the lift on the truck, yes you need to take it off...after the lift you can put it back on but it will sit low. this is why HO 04 is talking about brackets...if you do a search you can find more...
