98 XJ Frame Upgrade Questions

I have a 4-door 98 XJ w/ HO 4.0L that's in some serious need of some frame work:
- There are cracks in the driver side frame rail fore and aft of where the upper track bar mount is attached.
- And apparently, yesterday, when I was getting my heep (and all the mechanical work I've done on it) inspected at the local dealership, the steering box ripped completely off the rail as they were moving it around the parking lot.

I have been planning (needing) to do these upgrades for a while. But, as she often does, the heep has decided to make her own schedule. So, time to pull the trigger:
- I've been eyeing a full set of the H.D. Offroad Engineering Frame Stiffeners on the outboard sides of both driver's & passenger's side frame rails in combination with the JKS Mfg. Steering Brace System on the inboard sides of each rail on the front.
- I want to utilize both systems together because the frame cracks are not just on one side of the rail. In order to restore their structural integrity, the bolt-through/plate-on-both sides arrangement of the JKS Mfg. System is required.

HERE IS THE PROBLEM: As currently offered, the JKS System would no extend far enough back down the frame rail to effectively "sandwich" the portion by the Upper Track Bar Mount where the cracks are located.

Are there any suggestions, ideas, etc. as to how I should pursue this?
Should I be thinking of something else entirely?

Thanks for the help!

ps - I will post pics of this issue as soon as I can get access to the heep.

get some steel plate and cut it to fit the area and weld in place

I'm good with that for sure. But that would also require additional bolted/weld-through rods that tie the plates on each side together through the rail.

I guess I'm askin/lookin for is if there are pre-fab products similar to the JKS System that extend further back down the rail out there? Or, if anyone knows where to acquire the additional required hardware, if I did decide to go the custom fab route.

I'm going to call JKS Mfg. and see what they have to say about it as well.

Also, any general wisdom regarding this undertaking is welcome as well.

Take some cardboard, and mock up a rough pattern of what an extended piece would look like...
then fab your own out of 3/16" steel.... cut/drill/weld.... your done. if bends are needed, heat up the plate real good with a torch and start reefing/banging away...
5" of lift, 33's. Armored, Lighted, Chipped, & Locked up Front. Soon to come: winch, gears, axle shafts, and more...

Its not a bolt on affair, and I dont think anyone would make one.

I had the same problems. Tried a couple different fixes, all broke. Fixed it the last time, no issues.

TMR has front side plates, but you still have drill your own holes.
Also TnT has middle chassis reinforcement plates.
