I think I have the wrong starter for my 69 w/C4 trans. The partnumber (C7-#####-F) on the starter I have tells me that it went on a car with a manual trans, but I need one for a C4. Its never been installed on my car before so I'm not usre if it will work. How can I tell the difference between a starter from a manual transmission and an automatic transmission ? pics might help.
