Hello. I have a D16Z6 that I wanted to SC. I found a good price on a D16y8 that I heard would work. It came with the 3 rib pulley on the end of the nose, and I heard I would need to swap out the 3 rib pulley for a 4 rib. It came with the SC attached to the throttle boddy, the bracket with the 2 small pulleys attached to it, the large aluminum crank pulley, and fmu. I have a stock D16Zg and want to keep it stock, so I do not want to do anything crazy. just the stock JRSC 4 rib pulley that came with the D16Z6 would work. I believe it is a 6lb pulley? So like I said I think I just need the 4 rib pulley. If anyone has the pulley, please let me know.
