My mechanic is wondering if there is a timing plate that can attach to the alternator drive shaft on the IO-470 on my 1963 210-5.
Look in parts book assuming he has one. Many 470 and 520's dont have em. I heard some overhaulers were leaving them off too. The notch may or may not be on your pulley. If he can t make his own or use another method,,, i know what i would do.
