Nice looking work man.......!

Very nice work! Did you guys pre-heat all of the joints?

some yes, i used the same method i use to weld up off-road chassis and suspension. Mild filler rod (because its not getting heat treated) and a weave pattern. I just love to weld 4130 over 1020 anyday.

here is the shots of the romovable harness bar. It is made using special machined units that interlock and bolt together for the ultimate in strength.
