1980 14blt drum, with 2 thin nuts and cage to lock nut system in place, is on the bottom, vs 1986 M1031 system on the top picture or on the right on the second picture with 1 thick nut with key and C clip.
The spindle on both the 1980 and 1986 has the same stick out length and thread for the nuts are the same also.
Which is a better system?
Thank you,
Ed
