Original Dana 44 or Swap in Dana 44 w/disks

[Krex]

Question for everyone

I am in the process of doing a disk swap on my 1970 K20

Current axles is Dana 44 with drums BOM data is 603036-8 Standard 4.09 gears correct for year 1970 K20

Axles swap is a Dana 44 with disks BOM data is 603793-1 Standard 4.09 gears from a 1977 K20

So here is the question..... Should I swap everything from knuckles out to keep my BOM data correct for the year or should I not bother and swap the whole axles which would be easier for the rebuilt process since I am current driving my 70 k20 as a daily driver?

I know doing the complete swap will give me extra strength at the ujoints moving from 1310 to the 1350 ujoints
