I purchased a used bed to replace mine. They cut the bolts off underneath on the bed i purchased leaving the head still there.. the bolt is loose, bit for the life of me I can not pull it out. It comes out about and 1-1/2 and stops..it just spins around in the hole.

Does anyone know why rhe cut of bolt should not just pull straight out?

Here are a couple pictures

 

Just a wild guess, I don't know if the bed is threaded, but if it is and when the cut the bolts maybe used a grinder and it flattened out the ends? If you tried to extract is hit the end and stripped the holes? Does it still thread back in? Pictures may help.

So, this sounds crazy, but if you look at rhe picture, you can see the bolt but not the washer. The spray in bed liner was holding the washer in and it was keeping the bolt from coming through. I used a chisel and scored the liner around the washer and it came right out.

Thanks everyone for the help and suggestions! Great forum!!
