Yes, yes and yes, LOL. You should replace both trunion springs and end caps and the last picture that has the wear in the corners is where you will fill in with weld and then hand file it down. If that bracket is still mounted to the transmission, wrap a wet cloth around the lower shaft to help protect the seal from getting too hot. I would just hit a few tack welds at a time and not get it too hot too quick, then would file down some, then refill with weld some more till it was all squared up. I used the bracket in your first picture as my guide for filling in the second bracket. If you lay it over top you will see they are both identical in size and proportion. When they match you are good to go. Don't forget to use some shims on the first bracket when you re install it to make sure it has no movement and is centered over top of the springs.
