K2 Unnatural Inline Skate Frames, Wheels, Bearings

Took these off my K2 Unnatural's about 5 years ago and they've been in storage since. I swapped to K2 Uptown frames and never used these again. Unfortunately, 3 metal inserts seem to be missing from storage (should be 16 total, but only 13 are included – please see pictures). Frames, wheels, bearings, and the remaining inserts are all included as pictured. Bearings were never oiled. No screws or bolts are included. Wheels are K2 UFS - 60mm/88A. Bearings are ABEC 5. Inline skates are not included. Feel free to message if you have any questions!
