To remove the bolt with the rounded head I would try cutting a slot in the top of the bolt head. Cut the slot to fit the largest straight tip screwdriver that you can find. then use a pair of pliers or vise grips to grip the shaft of the screwdriver to put more torque on the screwdriver (it helps if the screwdriver has a square shaft. If you think that the bolt is too seized into the engine block to try that, another thing to try is to weld another bolt to the head of the original bolt, (I would use a wire feed welder) so that you have an undamaged bolt head to use a wrench on (preferably a strong socket wrench). If you do weld another bolt onto the original bolt, make sure that you let the bolt cool down completely because when you get the bolt hot, it will expand and will not break loose until it has cooled. Have a fire extinguisher handy and good luck. Hope this helps.

Hello. I can assist you. The black metal piece that you are referring to is a solenoid which allows the ignition to let go of the key when it is put in park. Remove the screws from under the plastic cover that surrounds the steering column. Next look along the ignition cylinder and you will see a spring loaded tab. Push that in and the cylinder will pull out. Now push in the new one and replace the plastic cover. Thanks for choosing Fixya! REgards, Joe
