Flipping a weight distributing hitch?

Hi all. I'm wondering if its possible to flip my WDH. (I would upload a picture but its a hassle here, I'm on a tablet only.) THe kind I have is the type that has the L part that goes into the reciever on the truck, that has three holes in it where the other part attatches to it via 2 big bolts (one hole is free, for adjustment I suppose) with the springs mashed inbetween. I got this setup when I had a much lower vehicle than I have now, and with the 2 1/2" lift I recently put on my truck I have to put a block under the front wheel to be able to crank it up far enough to get the trailer over top of the ball LOL. So what I'm asking is how difficult would it be to take it apart so the L part is now pointing down instead of up, put it all back together so the ball is 4-5 in lower. Is there anything special tool wise or procedure wise to do this, or is it as simple as it looks?
