Re: mercury Thunderbolt...

Do you know the serial number? If it has a red decal it is between a 1969-1971. Ingition parts are expensive. If it(decal) is blue it is a 1972 -1978or9, buy it if price is right. All yrs ran good,but the stator on the red ones are $300 if they go bad and they are starting to do to age.<br /><br />...have fun...corm
