So I screwed up royally driving out the taper pin the wrong way and a small crack formed on the boss as seen in the pics. Anything I can do here? JB weld? Do I really need to do anything as its not a stressed area? Thanks for any insight!
It's on the outside edge, well away from the spaghetti seal area. I think you'll be fine... As noted above, check for distortion to make sure it didn't throw things out of whack.
