THE BLOCKS FROM SILVER STAR ARE VERY GOOD, JUST DON'T LAST VERY LONG. I WOULDN'T ORDER THE BRACKETS THOUGH, I BENT MINE VERY EASILY AND THEY JUST BROKE OF THE FRAME. I RECOMMEND MAKING YOUR OWN.
I got a buddy that sells them, they are bad ass, and they last awhile, $80 for a set plus shipping, you will like them for shure, Let me know, send me an IM
