Re: 0.0 Is this a CRACK?!
Dude that frame cracked in two different directions.
It was stressed very bad or there is something wrong with the steel.
I wouldn't repair it, any welding will add localized heat and will change the temper of the
steel and not in a good way. I don't think you can normalize all that stress. It will crack again and in the same area. Perhaps brazing would work,,,
