4x4 Conversion Specific Questions

Hi Everyone,

Newbie here at posting but have been a member since 2015. I tried and tried for a search and have found a lot of answers but still need some more.

I am in the process of a 4x4 conversion on the truck in my sig by way of Frame swap with a 96 2500. My transmission is a 47RE 2wd and I don't have the transfer case, linkage, or driveshafts yet. My questions are really specific to sourcing these parts and doing it the right way. So here are some questions.

Please keep in mind I am trying to do this as a budget build.

1) Would you try and source a 4x4 tail housing and output shaft for the 47RE or just try and find a used 47RE out of a 4x4? I would prefer keeping my transmission because I know where its been and how its been taken care of but wanted to see what you all thought.

2) As far as 241 transfer cases are concerned, a 241D, 241DLD, and 241DHD will work correct? I have a chance to get a 241D but its just the case, so Id need to match the output shaft somehow, and figure out linkage. Any thoughts there?

3) Those transfer cases listed above have no electronics, correct? So if I fab up my own linkage it can be done fairly easily, right?

4) How would you go about this? Would you try and find transmission, Xfer case, and driveshaft all together? Or do you think the parts can be sourced used fairly easily by in pieces. And mainly cheaper?

Any help is greatly appreciated.
