THis fuse box is a one year only for 1970. Swap out a standard dash harness box & your in business. Now, dont get me wrong, I have seen this fuse box in some C bodies as well, you just have to do some homework & do some searching. I know of a junkyard right now that has a handfull of C -bodys with this box, maybe I should go there & hack a few off for members swapping this over.
