Couple 46rh questions

I’m putting a 369 magnum and a 46rh into my sons 67 Dart. Yesterday I test fit it to see how much tunnel work needs to be done and I was pleasantly surprised. I only saw clearance issues in 3 minor spots. I thought it would be a lot worse. I was thinking of cutting a couple things off the trans case but thought I would make sure the parts aren’t needed before I do. There are two parts that stick out on the drivers side of the bell housing that appears to have not been used in the donor truck as well as a spot on the rear passenger side of the case just past the pan. They don’t appear to cause any clearance issues but figured the more room the better if they weren’t needed.

first pic shows the three spots that hit the tunnel. Second and third show the parts I would like to cut off.
