Mazda rear leveling questions

Hey everyone, I have a couple questions... I don't want to slam my truck, I just want to level out the back of the truck... I have seen some 2-4 inch lowering blocks, and I am interested, but I don't want it to look silly like some of the trucks on google images where the rear is lower than the stock front. I don't want to change the front suspension at all. I just want a level look. My question is, to achieve this level look, should I go with a 2, 3, or 4 inch drop in the back? Does anyone have pictures of ONLY their rear drop? it's hard to tell from others' images when the front has been dropped too. Thanks for your help!

Park on a flat surface and measure from the ground to the middle top of the outer fender edge in the front and back of the truck. Determine the difference between the front and back. Likely will be a 1-2" block would be my guess.

you could always remove a couple of leaf springs if you didnt care about losing a little ride quality
