Does anyone out there know what the gear ratio would be in a 62 GMC 1/2 ton 4x4?
This is a parts truck and I am considering using the transfer case and axles to convert my 52 3/4 ton to 4 wheel drive.
Thanks for any help | | |

those axles will be a hare wide but if you use offset wheels it should look pretty good | | |

Haven't checked the front axle width yet. | | |

i've kicked around taking axles from a more modern 4x4 to convert my 52 3/4 ton too, and one of the issues is spring perch width. the frame on the AD is different width than the donor axles, and the donors are wider overall.
something else to consider is the end use of the truck. if you want to go wheeling, the travel before hitting the bump stops is pretty small. for just tooling around and the odd fire road it won't be an issue. | | |
