What do I need to do if the bottaom bolt of my front shock broke off? on 1994 Ford Explorer

Broke off during removal. There is still enough room to slide the new shock on, but not enough space to geta nut on.

believe bolt is made onto control arm. will have to have control arm replaced if it is.
Can't drill it out with a cobalt bit and replace it with a bolt & nut?
