Lowering Question
I am getting ready to lower my 51 3100. In the process of changing out the rear differential fluid I discovered that the previous owner most likely changed out the rear end and put in a rear end from a 58.
Was considering using 3" blocks in the back that I can order from chevyofthe40s.com for a 51 but I am concerned that they will not work on the 58 rear end. Does anyone have any advice or suggestions on the blocks or other ways? Thanks Andy |

Re: Lowering Question
More than likely they just swapped the center section of the rearend. The 55 and newer were spring over. The AD trucks were spring under with a torque tube. The AD trucks had their own proprietey brackets welded to the axle, so I doubt he changed the whole rearend.
To answer your question, yes the blocks will work. |

Re: Lowering Question
Thanks alot guys. You are right whitedog. The brackets for the springs are welded to the axle. Sounds like that is what they might have done. This may not be a smart question but why would they have done this swap?
Thanks again for the help. |
