Stop in for a cup of coffee

OK brain- trust... this has been banged around before... but I didn't get closure from the threads.

These from Summit are not correct for passenger side timing marks

65 parts manual shows water pump discharge is on the driver side for both the 273 and 318 and they use the same timing chain cover. Why would it be a different damper for the 318 auto?

Didn't get a final solution out of this thread

Or is timing tape a better option?


Any sources you know of? I've been trolling the interwebs but nothing with a high level of confidence

Anyone familiar with this one? 1947235 is shown as 273 or 318 standard transmission
