273 timing tab

A friend just found a super nice 1967 Barracuda. He is not a hard core mopar guy, and I am extremely jealous that he found this car for a reasonable price. But, I am looking forward to converting him into a Mopar lover!

The car appears to have the original 273 motor, but there is no timing tab cast into the timing cover. I am guessing the 273's had a bolt on timing tab, as opposed to the tab cast into the 318/340 timing covers.

Anyone have an idea where I can find such a piece??.

Please email, as I am not on this site often.
Thx!!
