In 1980, I was taking my Mother to a Cancer clinic in Mexico. After crossing the border, our truck hit a bump in the road –breaking a bolt on the exhaust system. I walked into town to discover the $600 part was not in stock. I used my favorite VISE-GRIP locking pliers to clamp the corner of the manifold and the exhaust together - stopping the leak completely. I was able to get my mother to the doctor for her treatment. 28 years later, I have the same truck with the VISE-GRIPS still holding the exhaust to the manifold.
