HO52 to 14 bolt

[c20pickup]

First time post here!! I have a 1970 chevy c20 2wd that is currently in frame off resto status haha started as a motor build. well in my search for parts for my h052 i come back with almost no parts, and the parts that are available are way over priced. currently the rearend is open, and im looking for a locker. Ive looked into converting to a 14 bolt, then i can have disk brakes, A locker, and have more parts and gear ratio availability. what is involved in swapping these rearends? im figuring i will need a driveshaft built, new brake lines, and relocate the sway bar mount. Any suggestions from anyone? there is the jefferson swap meet coming up this weekend and i will be on the search for a 14 bolt, what would i need to look for or avoid? this truck is also coil spring rear
