It is not interchangeable. The D50 arms are different lengths and bolt up in different spots IIRC. The leaf springs aren't the prob.
Bunch of threads on this topic.
Thanks. I did a search and didnt find any results. I might just buy a TTB for now and buy a solid axle later.
I can get any front axle for $150 right now at the local scrap yard and even though I won't have any flex; I think it would be much cheaper to swap to TTB than to have to fabricate and purchase all the things to do a solid axle swap.
No need just beef up the stock arms. You sure dont want 8 hole wheels. To much of a pain. New wheels and lots of cranking to change the tires.
The main advantage of the D50 is the bigger crossove u-joint. But the D44 joint only breaks when rock crawling. For that use do a SAS.
If you are breaking R&P put the D50 guts in the D44 housing. Works good. I dont see the need for that either.

Beef up the stock arms? Whats the point? The stock cast iron 2WD I beams seem beefy enough to me.
I was trying to find out of the D50 was interchangeable to I could convert my F-150 to four wheel drive. I may just swap in the TTb and buy a divorced transfer case, but I may not. My main reasons for this are the difficulties I am having while trying to align my factory suspension with a 2" lift. I would like to just do an SAS, but that would require a lot more work.
