I would only trust that repair to a repair shop that knows how to do full frame vehicles. My personal opinion would be to just find another frame. I had to do it on my first slick.
I would sandblast to start with. Then bevel the crack as much as possible. At that point actually straighten the frame. Id cut a pattern off the good side to see how much you need to move it. Once you have the frame where it needs to be, weld it solid from both sides. I would then clean up the outside to make it look decent, and clean up the inside. I would plate the inside area with another piece of steel, probably 3/16" thick, about a foot long, that fits the rail tight, top to bottom.
my 1966 shortbed does not have the large hole, only the 2 small ones.
thanks for that-
question: if you look back at my pic- notice how the bottom of the frame (to the left of the crack) has a lip that is sort of bent downward?
is yours like that, or perfectly straight c-channel? i don't have anything to compare it to.

This.
Weld it up...if you can't weld it, take it to someone who can.
now that we've got Carras' photo for comparison- here's what i *think* the crazy PO may have done...
i think he may have drilled the hole in the frame and used it as a retainer for the top end of the coil spring.
Good old Hillbilly overloads . They may have added the hole to keep the crack from spreading to the main section. I wouldn't weld the crack, I would put in a plate.

Mine has the bend that you mention
Here's a closer look. The bend makes room for the rear shock (not shown)

Yep. I'm a welder and this pretty much nails it. I've used this method on anywhere from log and dump trucks to light pickups and trailers and it has never let me down.

1965/78 LTD's have coil spring rear suspension w/a track bar. It's possible PO got a 9" from one, then tried to install the 9 and the coil spring suspension.

No, the pic shows the remains of a coil spring welded directly to the housing. OEM had a "cup" if you will to hold the spring.
