I have been shopping for an axel swap on my 1979 k5 blazer with fulltime 4wheel drive. I am going to convert my transfer case and hubs to part time during the swap/ From what I have found at the local wrecking yards the front 3/4 ton truck axle has the same shaft, housing, and gears. My question is can I convert my 1/2 ton axel to a 3/4 ton part time with a 8 lug pattern to match the bolt patern on the 14bolt 3/4 ton rear. I already have 373 gears in the blazer and I found a 373 14 bolt rear for a heck of a deal so I would like to keep my front setup and convert it over to a 8 lug pattern. Later on I will change both sets of gears at the same time. Is this possible or will I need to buy the entire front axel. The only one I have found has bad rotors and calipers so I would have to replace those. I figure it would cost less to buy all new parts for my front conversion if I could convert mine. I plan on running 38.5" tires so I am trying to get the axels setup to handle the weight and added torque of a tuned 400SBC and 4.56. Please help me out. I know you guys will have the correct info. Thanks in advance.
