My frame is cracked.

I tore the whole truck down then had it media blasted and still didn't notice it. I showed up to the paint shop today and the painter said that it had a crack in it. Sure enough. It is in the inside lower lip of the frame back from the power steering box. I think it is an odd spot for it to crack. In the first pic you can see where it is in relation to the steering box. I am going to try to pull it back together and then grind a v in the crack and weld it up then grind it back down.
