68 Barracuda 340 water pump , timing cover question ???

Here's a couple pics of the dampener. I see a part number on the back side 4173443 ? That part number appears to be a factory style replacement? Looks like it's missing the piece that goes over the seal in the timing cover? Could that be causing the issue ? there also appears to be 4 different timing grooves as well as markings most of the way around the dampener.

My car is an automatic.

512stroker I tried to pm you your inbox is full. Contact me YES I'd like the dampener you offered. An older style timing cover with the metal timing tab would be next as I believe I could tweak it if clearance is an issue?
