get 2 3/8 and 1 5/16. put the 5/16 in the bottom hole, and the 3.8 behind the headtube and in your folder slot. behind hte headtube it will be hard to get it in, but just get it lined up and bang it in there as hard as you can and it will work.
i noe thts wut i did i got both 3/8 in and the 5/16 but for some reason i think its my headse beacause like im grabbing it from the headtube and trying to wiggle it and it wont wiggle but when i grab it from the headset and wiggle it it wiggles
