I bought some BMR relocation brackets from someone off the board. They didnt' come with any instructions. I was wondering how you know where to put the brackets. So i looked on BMR's website and it says "insert supplied spacers into the original control arm mounts" I didn't get any spacers with the mounts. Does someone have these left over they would let me have. I would pay shipping, or is there something else i can use? Any help.
