On my 94 some idiot took off the powersteering pulley and teh belt tensioner pulley. Im about 99 % sure that the powersteering pulley is pressed on/off, but since I have to find a new bolt for teh tensioner I have no idea what size the bolt for the tensioner is or even looks like. I have no idea is its reverse threads or regular, any help would be appriciated

 

Salvage yard, and yes the power steering pulley is pressed on
