I'm working on a full time '79 f250 and was wondering what the easist or quickest way to remove rivets that are on the frame would be? and i'm not good enough with a torch to cut them off with one. The frame is a bit rusty so i most likely have to remove amost all the rivets to get the flaking rust out from behind all the brackets. Any suggestions? and we tried to look for a different frame but it seems like the ones near us are rusted to some extent. thanks for any help.
