    I think it looks fixable....
    First you need to cut off the bolt on scabs.
    Then mount a heavy bristle wire cup onto a small right angle grinder.
    Clean it up and see better exactly what you got.

    I have seen worse. X2 on clean real good then look for more fracture/tears.

    Yikes! That'll get your attention real quick. If I just wanted to get the Jeep back on the road as soon as possible, I'd do the following:
    -thoroughly clean and inspect all around the fracture
    -plan on likely removing the shackle mount/hanger in order to weld around the fracture
    -I'd also likely not be too comfortable doing any welding around the gas tank, so I'd take it out, which will also help you access the fractured area
    -not sure if bumper and exhaust need to be removed, but it looks like a likelihood
    -find a means of clamping the fracture back together (likely some large c-clamps and/or floor jack)
    -weld the fracture and add 3/16 mending plates to reinforce the weakened area
    -weld the shackle mount/hanger back on, being careful to measure that it's in the correct orientation

    I'm not sure what sort of use your Jeep sees, but I found frame cracks/fractures around the spring hangers and shackle mounts to be a chronic problem on my '72. The final straw for me was when I fractured the frame so badly that I limped it home with the left side of the frame being held together with a come-along. I strongly feel the only real solution is to fully box the frame. I also fabbed my own spring hangers and shackle mounts that now apply forces to a larger area of the frame of the vehicle. These early and intermediate CJ's are applying large forces to a very small area of an already wimpy frame. Not a good combination. Fixing the frame right was a time-consuming job, but I've found it to be very much worth the effort. Maybe do a quick-fix now, but start making plans for doing the job right at some point. I've got plenty of pics if they'd be of any help. Good luck!

    I plan on tanking the tub off cause it needs body work anyway. And the tank to. I plan to re do the jeep from the ground up. So it's going to be fixed right. I plan on going out the cracks so I can get good filler in it. And see how rest of the frame looks see wat I need to do to make it more reliable. Go check out the build. I got a post on It

    I fixed the frame in the '71, it was pretty much like that on both sides. Shackle mount had rusted through punched up into the frame channel.

    I cut off the last ~8" of frame, keeping what was solid.

    Welded in new steel. Added nuts inside as needed.

    Added a piece of 3/16 steel, bent in a "U", then welded stringers along the top.

    How to describe this? If your frame rails are horizontal like this_____, don't weld all the way across the rail perpendicular to that horizon. Better to fab a plate that is either fish mouthed < or > on the ends. Cracks usually occur when weld is put all the way across the frame rail 90* to the rail.
    And the fish mouth ends will actually give you more weld surface area. Or at least end your patch with an angle like /. Make sense?

    Yes it does I know wat ur talking about. That's how they weld truck frames together and same when they stretch mega cab to a long bed megacab. A curve in longer than a straight line

    I have done lots of truck frames, and all of the above apply. If it were mine, I would pull the body and tank. Make sure all replacement patches are at an angle and not in line with stress lines. I would also fab a u shaped inner frame insert that goes beyond your repairs, and bolt it to the frame, possibly stitch welding it along the c portion on the inside. Certainly repairable, but be sure to do it right.

    Before you get up to your eyeballs in it I would look around for a donor jeep, I got one for $200.00, that had a real good frame plus a lot of other parts I could use or trade. I took the frame to a sandblaster and had it cleaned up and beefed it up where I wanted more strength then primed and painted it, now the hard work was done and I didn't have my Jeep down long, one winter.
