Just picked up my new SQ-trim kit today. I took everything out of the box to make sure I had all the pieces. Obviously it came with the 8 rib crank pulley and belt, but for some reason I got a head unit with a 6 rib pulley on it! I have to wait til Mon. to call Vortech. In the meantime I want to make sure I have an S-trim with the wrong pulley and not an A trim. Does anyone have pics of the two different impellers? Thanks
