Sounds like a previous owner lost the original 9/16 nuts and felt that 14mm was 'close enough'. I encountered same thing when trying to remove the front bumper on my 58 Plymouth. I'll bet the threads are pretty stripped at this point. Probably worth running a die over them to try to reclaim the original threads, or just replace the bolts altogether.
