I did some research about possibly converting my 59 1/2 ton to 4wd. I had a Napco before and didn't want to go that route. I also didn't want to have tires that stuck out of the fenders.
The Dana 44 open knuckle fronts can be cut down 2 inches on each side giving you a front end that is 63.5 inches wide wheel mount to wheel mount. I wouldn't know where the perches would line up on an AD truck, but on a Task Force or blue chip truck, the factory chevy perches line up. This setup could give you disc brakes and a 6 lug pattern or 8 lug pattern
Ultimately I decided to keep my 59 1/2 ton a 2wd because I estimated the 4wd conversion would lift the truck 6 inches in front and 4 inches in the rear. I didn't want to be up that high.
