So I wanna install the rear bump stop extensions I got but really don't know how to take off those bolts without snapping them. These bolts never been taken off. I am afraid I will end up with half of the bolt stuck in the frame and the other half broken. Then I have to drill/tap and it will end up like a 12 X 1.25 bolt or some thing thicker. Question is, what's the best way to take out those bolts without breaking them? Or I don't really have a choice?
