I have 70 Jimmy with a D44 front axle that I twisted the left side shaft on. I went to get a replacement and decided to upgrade to front disc brakes. I acquired the new shafts, knuckles and brakes from a 72 Blazer. The problem is the 72 shafts are a little to long and will not allow reassembly of the hubs. The original shafts are long gone so I can’t tell if they would work. Anyone have any idea on what year shafts I can use? Nice bonus is the 72 shafts are a larger diameter than the 70’s, I wish they would have worked.
