You must find out if you have a 139 or 168 tooth flywheel before you know which starter to use. As you suspect, a 6v starter will not work on a 168 tooth flywheel and a 12v starter will not work on a 139 tooth flywheel. Once you know that, Jethro in Va’s post will come into play. Additionally, 6v starters work fine on 12 systems, as long as you don’t continuously crank on them. I’ve been running one on my ‘59 235 for the past three years. Good Luck!
