I read this thread awhile back, but didn't comment...
Cevigney, if your welding hasn't cracked anywhere (or near them either), and you've seriously "tested" them, go for it I say. I am curious if you used a 110v flux-core mig welder, however... if so you can burn hotter and tidy that up lol.
My first observation would be more based on the location of the 2" box tube (it looks like 2" anyway), that supports the passenger side TTB arm bracket. It really looks like it would rub the steering arm when the passenger front tire goes into a lot of up-travel.
Second observation would be that if the top of the box tube is welded to the frame... keep an eye on that, since the frame is designed to have some flex. It could potentially crack around that weld. Rigidity is not always your friend lol. Again, just give it a peek sometimes, it can't hurt.
All in all, the camber looks good and it appears you gave it more than 5 minutes thought... so my opinion (like it matters lol) is if you are confident, ride on bro.
