T56 AWD conversion So I just recently purchased an 04 1500 RCSB 5spd 4wd. I've been doing some research and decided to go with an awd driveline. I'm also wanting to keep it manual. Ive found that the awd tcases out of the escalades and denalis will work. The input shaft splines on the tcase are 32 spline and I'm wanting if i got a t56 and put a 32 spline output shaft with an adapter plate on it, would the rest of the drive line be able to handle it? Any thought? Maybe someone has tried this and can give me some advice.
There are a couple guys doing it. Essentially they use a C5 rear extension housing for it's ability to accommodate a bolt on adapter. I haven't seen any off the shelf solutions, all custom but it looks easy enough. Especially with modern laser scanners and cheap laser cutting services.
Been done before with a C5 rear extension and some mods. Here is a walk through on it with some pictures and details.

Call texas drivetrain performance. They have built several, and can get you setup.
Last time I inquired about having one built myself, they didn’t require a specific donor trans. I asked if they could build a setup from my existing magnum F, and they said yes.
