i didn't find the instructions per say, one of the guys said he got the type of grille for the job and cut it to fit and simply tie-strapped it to the back... i took the toyota grille off, easier to do this way.. and then made all the pieces to fit, use a dremel tool to cut or some wire snips... then just bend it around and what not, you can use tie straps, but i think that thin wire secures it better.. i didn't have it at the time... the bottom piece is the easiest to do... it is screwed in themiddle and i drilled hole in the support to fit a tie strap in...
