440 rear main seal... thoughts

I appreciate all the input from everyone. The 440 I took out was dry as a bone and it was in there for I don't know how many years and I did that the way that I just done the last one. But I got sucked up to the latest greatest foolproof things. And it may work for somebody. But as you can see it did hit my main cap and wouldn't let it seat flush. I was just under the impression that it was clearanced and had all of the issues removed from it and it would be a great replacement. Live and learn lol
You will send it back, and they'll just sell it to someone else.
