see i just took two peices of metal, measured cut them folded them with like a vice grip, did alot of measuring to find this stuff out, and hole punched holes in it to make the bracket. i didnt actually wire the thing in, i just cut the brackets myself and the face plate/bezel. i screwed it in and placed it there, then took it to best buy to wire up. theres a stopper in the back of the factory DIN hole that i had to cut off to make it fit right
