Opinion on 3 link frame bracketry

[mike18]

With the forces seen on an upper link under hard driving would you all think this style of bracket would hold up without pulling out ?
I want some upper bar angle adjustment and I do not want to run just a slot. Will 2 suffice ? What is the minimum material thickness from bolt hole to outside of bracket ? Should I maybe use 4 brackets and box a set of "outrigger" brackets to the mains for strength and bolt deflection ? Thanks for your input !

*UPDATED*

Went with a second hole plate that will be welded to the above. More beef to help with pulling out
