Frame Reinforcing Bracket

I posted this in transmission/drivetrain originally but it looks like I will get more help overe here.

I'm talking about the bracket that attaches to the frame and goes through the inner fender. This provides reinforcing for the ball stud. My car had all this but it was all hacked up as the previous owner tried to remove it when they went to auto transmission. Also cut a nice sized hole into the inner fender so I'm not sure where new would would line up.
My question is, when i get a new bracket what is the best method to mount it. Do i simply line it up with the hole thats there, weld it in and it';s good enough? or does it have to be perfectly aligned. Does someone have a picture of it that could maybe help or dimensions.

Another random/easy question. Is there a brace that goes under the transmission to provide support? I'd assume yes, but wasn't 100% sure.
Thanks!
