I think i need a different drop

I don't have my tundra or my tacoma anymore but the wisdom is here. I installed pro comp lift shocks (2.5") and a 1/4" spacer (1/2" lift) on my new Silverado. After the install it looks like I'm going to need to do a differential drop. Pro comp said I wouldn't need too but I think the angles are bad. Opinions? The truck is parked on a slight grade btw. I'll take some flat pics tomorrow.

First picture is the passenger side. This is the side on about a 5 percent grade. Alignment is tomorrow


Drivers side. Slightly up hill

 

I think im gonna do a sway bar drop as well.
I have 1" spacers for the diff but it is more difficult than my Toyotas
