Re: what rear end do I have
Yeah I guess I should have clarified that as to what rear end is in my truck,,,,Naa that could be misleading also, maybe what gears do I have would be better.

Re: what rear end do I have
if is is a small block with an auto, it'll be a 3.07 onless chainged out or otherwise listed on the SPID label.
Popping the cover off and counting the teeth is a good way to see what you have, the condition it is in, and replacing the oil since it is of minimal value after so long. |

Re: what rear end do I have
before you go nuts counting teeth, spin the ring gear around and look for a bunch of stamped numbers. if it is a GM gearset it will have the tooth count stamped on. 41-10=4.10, 41-11=3.73 etc, just divide the two.
