4430 salvage rebuild Saga. Need help with rear end swap

Ok. So I picked up a early basket case 4430 (sn: 4430p 011616R) for cheap. It had the rear end blown out of it. It came with two rebuilt clutch packs and a salvage rear end from a big salvage yard ready to be swapped in. After getting it home I seen that the salvage rear was from a 4230. Same casting numbers on the housing but some of the internals are different. We found this out when we were cross referenced the part numbers for the bull/ring and pinion gear cage and sun gears that then slide into the planetary. All the part numbers are different. So I need a little help figuring out what to do. Should I swap out the new updated bullgear/ ring and pinion to the older one it calls for in the 4430 manual or just keep the rear end together and put in new sun gear, ring gear in the outer axle, and outer planetary? Or just buy a complete salvaged 4430 rear end. And forget about the 4230 rear and take it as a loss.. I've attached a couple pics of the serial numbers

Darn spell check changed my numbers and they won't let me edit my post.. the spare rear is a 4230p sn: 029497R
 
Yep, they are the same. Where I'm getting all screwed up is that carrier that the ring and pinion bolt on to is different, the spider gears that suns gear shaft slides into and the shaft itself that goes into the planetary. JD kept updating the rear ends on the 30 series because they kept blowing them up.. then I measured the sun gear shaft (goes from the spider gears to the axle planetary) they all measure different. As the serial numbers go up. So should I just swap spider gears, sun shaft, and planetary and call it a day or find a old rear end and throw it in even tho it's weaker.. or just go find a 4430 rear end all together and trash the 4230 rear ??? Ehhhh just kind of lost on this one..
 
I am just now looking at your problem,,I think that what your having issue with is what I call the differential bearing quills,,they were changed at a mid way serial number and you may have the correct one in your mix of parts,,I can research it better for you Friday nite when I get home from this 2 week road trip..
