Toytec coilover setting

Ok, so I bought a set of used toytec coilovers with the stock top plates from another member. He was not sure how much lift they were set at because his truck had spindles. So my question is in order to achieve 2.5 to 2.75 inches of lift on my double cab long bed, how much do I need to crank them up? In other words, how much thread on the adjustment perch should be showing in order to achieve my desired amount of lift? What do you guys have your double cabs set at? Thanks.

 

I have one inch of thread showing not including the adjustment nut, to give me 2 1/2 inches of lift. This is how they came from toytec adjusted at 2 1/2.
