I would watch some video clips(expert village) on doing this before attempting it for the first time that way you have a idea of what procedure to go through before trying it.that said unless you have to mess with retarding or advancing the timing you should just be able to unclamp it and pull it making sure to mark the wires and the distributor position towards the first spark plug(number one cylinder) so you can put the new one back in the same way you took the old one out..www.ehow.com
