I think it would fit using the plastic cover but I didn't do a lot of thinking about it first. I had to cut the end off the crank and thread it 3/8LH and I guess I could have just moved the 7/16LH inboard and still could if I want to use another crank. The 8500 has 1/2LH thread and a different clutch spider that you can get but the 8500 is hard to find
