Wide track axle conversion question

I've got a spare set of wide track axles that I want to put under my 75 CJ. Why? For the extra stability, front disk brakes, and looks. That said, my question is for anyone who has done this. I know the front is a straight bolt in and I know my shock options as I also have a spare set of towers and plates. But the rear is where it gets tricky. The rear spring mounts on the frame are the same distance apart in the rear as the front (roughly 28.5 center to center). 76 on saw the wider frame in the rear with the axle flange being a mere 4 inches away from the leafspring pack and the wide track axles then saw 6 inches distance. After welding in new spring perches, the wide axle on the narrow frame will set the flange about 9.5 inches away. IS THIS TOO MUCH DISTANCE..IE LEVERAGE FOR AN AXLE MOUNT? I will be using a Model 20 with no lift and stock sized tires. The end result will have the springs just on either side of the diff housing. An option is to move frame mount outboard of the frame. Would this be better, anyone done this before in this type of situation?
Thanks

I'm running a 65.5" wide Chevy 14 bolt on a CJ with the same distance between frame rails. That's about 10" wider than a wide track. I have seen no stress come from this additional leverage, but I do have the frame boxed from front to rear. I will tell you that it flexes like mad!! You wouldn't be the first to do this, and I've never seen widetrack axles overstress a narrow frame in over 20 years of Jeeping.
