:I am trying to get the exhaust manifold off my 71 Grabber project car so I can repair an exhaust leak, but I've already twisted off one bolt. Y'all have any advice for me --besides leave it on ;) I would like to keep the engine in good shape and running so I can try to sell it when I finally pull it from the car, so I don't really want to twist off all of the manifold bolts trying to get them out. Do I have any hope?
