What about upgrading the rear drivetrain on a 64 c10 short stepper?
We changed out the front from a 76 GMC. Now it has 5 lug wheels, discs and power steering but the back half is still 6 lugs with 3 73 gears.
What options should I consider?
Thanks in advance. | | | | | Joined: Aug 2004 Posts: 1,418 ODSS Lawman | | ODSS Lawman Joined: Aug 2004 Posts: 1,418 | With 3.73 gears, I'd let it be. If you go too tall your truck will be a slow turtle.
Provided you have a stock engine of course.

Alternatively, if you can get the rearend from the donor truck that the frontend came from, you can either use the entire rear by putting the mounts frm the original rearend on it, or you can get 5 lug axles by simply having the shafts from the donor truck cut down to match the originals, then grooved for the C lock. You will also have to use the side gears from the spider set, as the later axle is 30 spline vs the 17 spline of the '64. The parts will interchange.
