1984 K3500 nv4500 install

[52 Chevy]

I have a 4 door dually 4x4 454 4 speed that I want to drive more.65 is wound up. I have a 95 nv4500, the t-case in it, and also a 241c. My questions are...

What clutch combo do I use?

What is the best transfer case to use?

What bell housing?

Basically what all parts do I need to do it right?

I know some of you are going to tell me to research it and I have and most seem cobbled up to me. I want to hear from someone that has actually done it not someone who read about it somewhere. in the future I also plan to pull the big block and go with a 6bt. Thanks in advance.
