U&L Torque box reinforcement's?

[Igofaster13]

I need to get U&L reinforcement's for my torque box's. I have a flux 90 amp mig welder, and was going to bolt them in as well, you think that will be fine for the install? I will be installing upper and lower boxed steel control arms, eb. springs, sub frames, and a kenny brown lower chassis brace.

it will work but if you can use the shielded wire with argon it would be better

Cool, I will get some. Is it expensive wire?
