Mark each wire with a number then remove one at a time! disconnect from distributor same way place tape with numdr on it at distributor,then match up to ne wires as for size etc. using same method tape number to them.
Remove and replace spark plugs at same time make a note of date etc.

From the plugs get a puller, which is an inexpensive tool and can prevent any damage to your wires.
