Think I need lower blocks to even out my 67's stance

[AJLChase]

I ordered a kit a whole ago from Brothers, which took forever to get all of the pieces ( even received shocks 2 years after I cancelled the order). Well at first I started off with a 5" front and 5" rear lowering springs/shocks/drop spindle setup. The front was way too low and everything grinded. So I recently put on just a 1" spring to give me 3" total and my truck looks better in the front, but the ass end is hanging up really high still. I'm almost starting to wonder if they sent me the right rear springs to begin with. Looking at other 3" & 5" drop pics they seem to be more leveled out, which my truck isn't at all.

Anyone else run into this and what blocks do you recommend?
