Can't get timing dialed back to tdc
you either have to pull the distributor and move it one gear tooth if it's "really" too far
Or move the plug wires which is not 'by the book'
And yes, for smaller movements, loosen the bolt going "up into" the distributor and move the clamp device
Some had a clamp like this
Others had a second slot and bolt up into the dist. body
