1962 C30 disc brakes conversion???

[62c30]

Anyone know of a 8 lug disc brake conversion? I have not found any online for the torsion bar frontend. Or I have thought about swapping the frontend and rearend out of a 1981 GMC dually i have as a parts truck. I have not looked into the swap much cause the parts truck is in another state. I use the truck as a work truck still and the drum brakes suck even when not hauling/towing and even worse loaded down. Any help is appreciated!
