i know little or nothing about the D35 spcifically, however, in general...
I would have a hard time moving internals from an axle with a bent tube to another axle. The mis-alignment in the shafts is likely to cause issues with the differential bearings, side gears, etc...
Cherokee axles are all over in junkyards. Is there a reason not to just swap the entire axle?
And I do have experience with disc brake conversions... It takes more than a couple of calipers to make one work. The proportioning and residual valves are very different. Running disc rears on a drum master cylinder is likely to cause major rear brake lockup in a panic stop. Resulting in a nasty spin, nearly wiping out a Sherriff's car, and buying a guy a new front porch... Not to mention street sign, lawn, and vehicle damage...
Some day, I'll ask 17 year old me how he learned about brake conversions... Right now, he is still working off that old debt...
