Truck is 6 lug, drum brakes all around

Intending to use it as a daily driver / cruiser

One opinion is to swap the rear end (with what, TBD) for something that’s 3.73, disc brakes and 5 lug; then make the conversion on the front to 5 lug with discs using a kit.

Another opinion is to keep all as is except converting the front to disc brakes.

Any strong opinions one way or the other from the group?
