I have a 78 chevy full time 4X4. my trans went out a few weeks ago. it has a turbo 350 with a 203 case. It is completely stock. I just bought a used transfer case and trans for $100. They seem to be in good shape. Here is the problem . . . it came out of a truck that had 3/4 ton axles (i think) and had hubs on the front axle that you lock or unlock. Had this one already been converted to non-full time setup?? How can I tell?? What exactly had to be done to convert it? What if I didn't change the hubs on my truck and used the case converted over already on it???
