Ditto, get quality builders parts.
I got my weld through recovery tabs, latch, swing arm greasable spindle, 2" tow reciever, and other parts from comp4x4.com.
It saves a ton of time, isnt very expensive and is like a big jig saw puzzle.
I used 3/16" steel on the bumper face. And 1/4" on the frame mounts and gussets
And 5/16" on the swing arm. Which seemed industry standard for my vehicle when compared to other aftermarket manufacturers.
Also gusset and reinforce everything. Be prepared for flex during heavy trails and long towing situations.
I added a secondary locking pin to the swing arm to reduce flex and create a redundant system.
