Just a little update.
I have the Dana 80 rear from the 1994 Chevy 3500HD truck installed. I have the spindles/front disc brakes from the 3500 HD installed. I had to source rear steer arms (which I think is the most difficult part of this swap). Ironically, the original COE tie rod and tie rod ends fit the late model steering arms. I did have to machine the original front axle slightly as the king pin ends were slightly too tall and I mean slightly, with no shim. I am "planning" to use a reverse rotation steering box from a 1978 Dodge W100-200 which mounts to the SIDE of the frame in a cradle. The pitman arm is also sourced from the same vehicle to fit that box. I have not mounted the steering box yet because I want the full weight of the body and bed on the truck first so I can keep the drag link relatively level. I will have to fabricate the drag link. I am going to run 1" steel adapters to adapt to 22.5" Alcoa wheels. Duals would be too wide in back, but I found a super single wheel with a nice offset and like new Michelin tires, so that what I will be running on the back. I had also found a set of 22.5" RV wheels which are narrower than Semi wheels. I felt this was important on the front. I would have rather run the Alcoa RV duals in the back but it looks like they will be too wide. I am waiting on an adapter to test fit before the other 3 are machined.
SO that's where I currently stand. The 9R22.5 tires are slightly taller than the originals and the tires on the super singles are also slightly taller at 40" from stock, but I think the truck will look better than trying to run 19.5" wheels which are 6" shorter than originals. We'll see what shakes out in all of this.
