My left middle bed bolt likes to spin even with the nut and clip in the proper location. Ended up using a rubber mallet, couple medium wacks and she was able to thread.
Edit: btw the original bed bolts are 1 time use. Should be replacing them every time you take off your rack. Highly recommend upgrading to khc bolts
