So after a long few weeks of getting the wrong part, sending it back, getting back ordered then cancelling the order and finding another sprocket at a different store. Ordering and waiting again. Got the right sprocket (42T) vs the 40T on there now. Put it on to be 1 link short...........DOH!!!! So I ordered a 150 link black chain and waited again..........The payoff just hit my door step. Time to put it together tomorrow.
