Looks much better OP. Where did you end up going to get it done? What'd it run you?

I took it over to miltons paint and body off of warwick. The place looks ghetto but they have all the high tech frame stuff. He welded the cracks in the frame and threw it on that special frame computer to show dimensions for $300.

that weld will never crack again,metal next to weld might.

@csp , you keep throwing dirt on a vertical weld...what is the alternative when you have a vertical joint that needs joined?
I was curious so
"On light truck frames, the procedure is similar to what was mentioned for tubes.
A crack on a flat surface is reinforced by a diamond shaped plate. Same thickness as parent metal. If the crack is 3" long, make a square that is 3.5" in the diagonal and have the diagonal cover the crack (you will have to grind down the weld - so a 100% penetrating weld is preferred.)
The idea is to spread whatever stresses caused the first crack around a bit.
If you weld a square plate over the crack, with square edges parralel to the crack, the same forces that made the first crack will now be concentrated at the edge of the square plate. If you rotate that square plate 45 degrees, the stress risers will be at 45 degrees to the original crack - effectively spreading them out.

Where the vertical line is the original crack. Call it a diamond, call it a square rotated, (call it a rhombus). whatever. "

Vertical weld on the vertical joint with a proper fish plate on the outside. Notice the rounded corners as well.
I never said a thing about "pretty". However, since you brought it up most of the time a good weld (one void of porosity and undercut for example) IS pretty.
The repair may not be "by the book" correct, but it's not like the crack originated under normal use and fatigue, it originated from a crash... The fix is fine for what it is doing and the small forces it will be seeing.

Missed that before, that and the term fish plate sounds like jibberish to me, lol. Thanks for the info though, I feel like that is good knowledge to have
