Re: Need help
Welcome,
I believe that is a 63 Though I don't find the exact number.
You could try Langs Outboards,the Chrysler crew, or
www.aomci.org they have a free webvertize.or keep watching ebay.All kinds of obsolete parts show up.
West Bend was bought by Chrysler C: 1965 so early Chrysler parts may fit.
I'm probably not at the right spot but maybe someone can direct me to the proper link.
