Sorry to overthink this but would they have the conical base? That seems to be a pretty specific item I couldn’t find at HD or Lowe’s which are my hardware options.Any local hardware store. Just take one in the store and get a matching thread. Get help from a person who works the floor or lay the threads in each other to make sure they are identical. If you need to drive your Jeep there, put 5 in the skid and you’ll be fine. Buy stainless to avoid future rust as much as possible.
I have another vehicle so I am good.
I could always put these in and then order the specific ones online and swap them out later
