I just bought a 02 four door blazer and put a system in it. The problem im running into is that i cant find a install kit that fits. None i have tried will line up with the bolt holes. I have it rigged for the time being with zip ties. Its just a clean blazer and a good sounding system and i dont wanna leave it rigged.

 

I wanna say that a double DIN dash kit should fit. Thats what I put into my 2002 and it fits perfectly fine. It's not a dash kit made for a double din head unit, it has a single din slot with a storage compartment below.

 

Thats what I did on my 1995 also.
