4R100 tailshaft questions

Hey guys!

I am about to embark on a 2WD-4WD conversion on my 99 F350 PS. I got an entire truck to use for parts, but I have one question/problem. The truck that I am picking up is a manual and I have an automatic. From what little I have read, I see that most people say I need to change out the tailshaft from the 4WD transmission. I will obviously need to get that piece, but I was wondering if anyone knew if this was necessary or not. If so, I have a lead on a shot 4R100 from a 4WD F350 that I could rob the shaft off if it is not too much work. Do I need to dismantle the entire transmission to do that, or does it just bolt to an output shaft on the rear of the transmission?

Any help would be greatly appreciated! I also plan to post pictures of the conversion after it is complete.
