i do belive the front lower motor mount bolt has a nut on both sides and the threaded part is a removeable stud. it is removeable by slideing it out , or in your case braking it loose to slide out. pb is good. but you will have to use a mallet to get it to start to move and soak some more before it comes out either the right or left side. yes they do get stuck good too. hopes this helps.
