Well the pin thing fell off of my shelf and three of the six bolts sheered.This also caused most of the pins to fall out.

Step 1: The Fix.

Re-insert the pins in whatever fashion seems to take the least time for you one by one seams simplest. I used the three bolts that remained to hold the two pin holders together.

Step 2: Screw It

Then screw the bolts into their correct possession with the spacers in place. I found some spare bolts that fit the holes (well my dad did) but I would recomend you do this and if the bolts are metal instead of the plastic bolts they shouldn't sheer in the future.
