I bought one from you not knowing the marks are on the passenger side. It's for my '70 340. Can I still use it by just putting a 7 1/4" tape on it? FYI, it's a beautiful, quality part. Paul.
You can do that as long as you know where TDC is when you install the tape, or you could just switch the timing cover over to the other style and no tape would be needed.
