I started to rebuild the rear suspension of my 1970 BGT last night, complete renewal of springs, shocks, the works. And, as you can most likely guess, sheared off the stud of the lower rebound strap. I stopped after that and poured a tall cool one to reflect at what happened. My question, other than WD-40, anybody have good advice on freeing up fasteners? I really do not want to break any more. Thanks in advance.
