Truck leaning..I Have an Idea..need opinions

[poov71]

77 SWB.. Lowered with 3"spindles and one inch coils.. Rear is a flip..
The passenger side rear sits approximately 1 3/4" higher.. The front of the truck is spot on and it does not appear that the cab is unlevel. The bed is tilted about 1/2" lower to the driver's side which accounts for some of the issue. That leaves 1 1/4" to address.. So..

1. Shim the bed on the driver's side to gain the 1/2" lost there? Anything wrong with doing this?
2. Could I remove a leaf from the passenger's side (only) to make up for some of the height difference? Is there any issues with doing this? If not, which one would you recommend removing?

Thanks you for your time and advice..
