My 70 has open knuckle w/ drums and my 71 has open knuckle w/ discs, you could just swap everything from the knuckle out but usually it's easier to find a complete front axle from a 71-87 truck or -91 for blazer / suburban. It was thought that you could swap spindles and backing plates from a disc 44 to a drum 44 but it clocks the caliper back or forward depending on how you put it on. On a closed knuckle front you will not be able to convert to discs. I had a lot of pics but they are on another computer w/ a virus! So after the storm I could shoot some pics.
