Anyone use this In a 84-90's Chev?
 

I curious if anyone has used the "EZ 21 pre-wired 21 circuit GM style fuse block kit" to replace the hacked up jobs PO's have done to the trucks before you owned them.

Still debating if I want to go through the hack job that was done on my truck or if I'll just gut it and replace it with this kit.

Anyone try it? or know of someone that has? any issues? my blazer is an 84
