Tie down bolt specs

What are the specs for the bolts for this bracket? I need the short bolts, not the longer ones used with the tow hook configuration. Thanks!

 

I can tell you to NOT install the stock bolt without the hook. The bolts threading stops, you will over thread it with the impact, then cross thread it backing it out striiping the theads. then you need a new bolt but stick a piece of wire in it first so it holds. Just to let some know who remove it.

 

I think I’m follow. Are you saying that this assembly can’t be reinstalled without the tow using the short bolts that are on the driver side bracket? Seems like it should work in theory.
