Rear Lift Block

I'm getting ready to fix the taco lean on my truck. Right now with a full tank of fuel the driver side rear is sitting 1.75" lower than the passenger side and the front driver side is about 1.5" lower than passenger. I've got the bilstein leveling shocks in the front so I'm going to use those to fix the front end. For the back end is it as simple as a lift block and longer ubolts? Has anybody else used something different? I'm not looking to spend a lot of money on this project. I was even thinking that rigging up a hockey puck in there might work just as well.

 

Or would replacing the leaf spring shackle on the driver side with a longer one be a better idea?
