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
