Thanks everyone for your reply's! From what I am seeing here then it looks like they are the same bolt that my 72 E-body lower shock bolt is then. Surprising that Mopar actually used the same size bolt on more then one vehicle, that's why I asked for help here. Thanks again!
Those shock absorber bolts haven't changed on the A, B, E, body line of cars from 1962 to 1976 that i am aware of, when Ma Mopar went to this type of lower control arm front suspension.
