I think if you put an actual strain gauge in that area you would find that a grade 5 in theory would work.
I've done a little strain and breaking analysis just in seeing how much torque it takes to strip bolts and break them. You would be freaking amazed how much it takes to "shear" a bolt, I don't think a Ranger has the weight to do it, even pulling trailers and hauling loads within specs (which are conservative a lot of us have discovered).
Material and heat treat method has more to do with shear than the "grade" of the bolt. I guarantee you can drill right through those rivets and they never give out.
I'm sure most fabbers with a welder probably throw a bead on there after bolting.
I would trust the bolts myself, if I do try this I will just rely on the bolts. There is more torque on your engine mounts and it is held down with one nut on the frame side.
Just typing out loud!
The "give" is what I was thinking of, grade 8 and above will just pop instead of stretching.
Does one of the frame sections, fit inside of the other, that would lock things up some.
Did you get a chance to read that post on the other Site ?
They have the truck next to each other and you can see a lot of frame info.

ADDED:
Was looking at the other Thread/Site, it appears that the frame sections do interlock, that alone should reduce the shearing problems.
If I wasn't already into this '03 Short Bed.std Cab, that could have been the next project.
The color, Quicksand Tan, I was thinking on repainting my E4 RED Ranger in that exact color, now at least I know what it will look like and I DO like it.
Another thing added to the project, if I can only get my sh!t together and start it !
