Suspension question

#1
My daughter was in a minor fender bender with her 04. She managed to bend the passenger side lower control arm and inner tie rod end. In the process of removing said lower control arm I twisted off the head of the forward pivot bolt. This looks to be a blind bolt hole, can't find access to the nut. Any suggestions on getting the bolt out? Anyone know the proper name of the sub frame that the A Arms mount to in case I have to replace it?
