I will say - anything is fixable with time and $.

Lks,
So I measured before I bought the Blazer and my numbers are about a 1/4" greater to almost 3/8" greater in some spots based on the numbers in the photo you attached above. I thought that typical "sag" that is always mentioned would show the distances to be less than those listed in the photo?
