Is an automatic transmission dust cover needed?

From what I have seen slants don't have the small plate.
My 73 318/904 does. (not sure why some do and some don't besides the drain service)

The small cover hole can be welded up if that makes it more convienient.

From the picture it looks like he has the passenger side brace, and I got that one back on without too much trouble.

Good to know Trailbeast. I'll never get these Chrysler parts figured out 100%. There are so many variations.
