Dale, yes replacing the seal will likely help stop your leak however you need to determine what caused the seal deterioration. Was the engine stored for a long time and then started with the seal rubber dry?
I cannot tell if that is a Terry Burtz one-piece seal, but if so you will need access to the entire rear flange of the crankshaft. Also, I would want to see how they are controlling the thrust of the crankshaft. That might have been a contributing factor for the seal failure. I do know that the craftsmanship on that engine seems very rough just judging by the reliefs that were "carved" in with a cut-off grinder for the insert shell tangs.
I will close by suggesting that you be cautious of the advice you are getting over on social media. You have everything from a former lawnmower mechanic to folks who don't even own a Model-A (-much less worked on one) giving you advice.
