I am sure you will be fine with a simple L bracket out of 1/8, I don't see a need to reinforce it. The sparco seat brackets have a tab for the factory seat belt and it is just a simple piece of 1/8 flat stock welded to the bracket.
As long as the welds are good, or the bolt you are using is good I dont see an issue.
