JC Higgins front fender mounting

[mike94yj]

I am trying to mount the front fender on a late 40's higgins. Should there be some type of fastener in the fork to mount the fender to? This bike was disassembled 30 years ago and I don't know if I am missing something. Thanks

Tried to take a pic , not much to see but a 3/4 inch hole in the bottom of the fork. I think I can install some kind of expansion not if that is what it needed.
