It looks like you have no bed? How much of the rest of the truck is missing that you plan to replace? This will all affect the shackle angle.
I think you'll still have a problem with it how it is now just because it's a stock shackle which doesn't allow for much movement. Your lifted springs will become much "longer" than stock springs as they are compressed, which is where a longer-than-stock shackle would be nice.

You know you are absolutely right! I have not considered the weight difference at all. there is nothing here but frame. All sheet and running gear but axles is removed. Are you talking about using something like a shackle from sky?

That forward position is about perfect if the weight of the frame is actually sitting on the axles there. When you add the weight of the bed it'll add about 10 degrees to that shackle making your angle right where you want it. I would drill your 2 new holes and run it there. If these are brand new springs they will settle over time and may flatten out a bit. If they do you can build or buy new longer shackles to compensate. The truck shouldn't dip really . . . you've taken out a couple inches of block and increased a couple inches of lift with the shackle flip. What's done on the front is a shackle reversal and is completely different. A reversal is where you move the shackles from the front of the front leaf springs to the back for a smoother ride. I don't remember on your year of truck if they came up front or in back.
