I was attempting to do the Mr Gasket advance spring mod stickied in this forum, but the directions dont tell you how to completely get to the springs. I am new to tearing down distributors and its various internal components.... must you press out the roll pin on the armature on the dizzy shaft to remove it in order to get the cover plates off to access the springs? Cant get it off and it appears it must be first removed to gain access. It is the component that is shaft mounted below the rotor with the 6 spokes to indicate firing via magnetics. Thanks!
