what is this bolt called?

my new to me 4runner is missing a bolt near lower control arm and need help finding out what its called and where i can find a new one ? thanks

 

What perspective are we seeing? Sort of looks like your front cross member near your diff or a side profile looking like a trans/transfer case support. but I may well be wrong...

 

This is the front crossmember in front of the passenger cv axle and dif

 

Easily your best bet for getting an OEM replacement is just go to a junkyard and take a bolt from that exact hole. Did that on an old car when Firestone offered to cobble together something for $50. Cost me the $2 entrance fee and was the exact fit.

 

I see what appears to be a Bolt missing from the Sway Bar on the upper Left .....
