Doing my RMS and pulled the exhaust right after the manifold. 2 bolts came off okay, 1 snapped, 1 had to be cut after it bent the tab then sheared the tab off. so definitely want something new and stronger. any tips besides regular nut and bolt? not a fan of the idea of having to pull my intake manifold to access these again were i to put a regular nut up top as there is no way to get a wrench up top without pulling the IM in my personal experience
