I am restoring a 1962 Mercury 450M and the tiller arm part was an accessory for that motor. I have searched for the original part and come across only 2-3 and missed out on purchasing it for various reasons. Is there a conversion that will utilize another tiller arm assembly without drastically affecting the restoration process that anyone can advise me with? Im searching non stop for the original part and miss it by seconds....hope to get some answers - thanks
