If all else fails use the test light method, turn crank to top dead center or the factory timing mark aligned with the crankshaft timing mark which ever you choose ,remove the dist. cap and rotor, connect a test light to the wire on the points turn on the ignition loosen distributor and turn distributor where the test light just comes on ,this is the most accurate way to set the timing with the timing marks on the crankshaft to timing cover , re assemble with the distributor clamp tightened and vacuum advance disconnected, check the reading with your timing light, as we know the Load a Matic Distributor does not use centrifugal advance, the timing marks should read very close if not on the mark due to any small variations caused slack in the timing gears due to gear wear or cam walk (end play) in the camshaft.
