Not gonna happen, try to losen or tighten and for sure, all of them will just snap right off, maybe 1 will move but have no threads once lose, having to drill n tap new ones. Which Buick still did too.
I took it one step farther and drilled them out completely to use a nut and a bolt, knowing they will just freeze up and break off on removal, much easier to do that way, no drilling each time.
gonna cost money as it will be a job in the tight spaces.
