I bought a 1 ton front axle a while back from somebody that will remain nameless (but he runs a certain wrecking yard that most of us are familiar with) honestly we all thought it was a 60 till Jason ran the numbers. Anyhow, now I am getting ready to put it in and am trying to figure out how to run the gears Jason gave me from his axles and I'm lookin for any info any of you might have come across in your travels. I guess I'm more lookin for opinions rather than experience being that not too many people try to use these axles but its what I've got so I'm gonna try. I found this on east coast gears sight and I'm havin a little trouble trying to decipher it but I'm thinkin its sayin I gotta cut some huge ring gear spacer to make this thing work. The gear I have is a 4.10 d60 gear and I'm wanting to fit it into a d61 with 3.07s. I'm not apposed to makin a big spacer, I'm just not too clear on just how thick I have to make it for the application I've got.
Gearing:
This is how you get one to work. There was a a dana 60 spacer made by Reider that allowed you to run the lower ratio gear ie 4.56 and up. I believe this spacer was 5/8 thick. It required the 4.56 and up dana 60 carrier and the ring gear spacer to get the offset needed. This said spacer seems to be just a legend now and has been discontinued. However their still is the Mr. gasket dana 60 spacer (5/16 thickness) that just about every drivetrain company sells. This spacer is designed to allow you to run the 4.56 and up gears on a 4.10 and down carrier for a regular 60. This spacer does come into play but need not be confused w/ the legendary Rieder spacer, they are of different thickness.
Alas there is a dana/spicer Dana 61- 3.33 and up carrier part# 706400x. This carrier is 2 3/4 tall. Where as the dana 60 4.56 and up carrier part# 706041x is 2 7/16 tall. So what combination do you need to run which gear ratio? If you have a dana 61 that has 3.07 gears in it and you want to run 3.33-4.30 gears, you will need to run the dana 61 3.33 and up carrier part# 706400x or the dana 60 4.56 and up carrier with a 5/16 ring gear spacer. This is popular for people who are trying to regear a 3.07 dodge cummins and the like front 61 that has a non overdrive auto, If you switch to a manual or to an oerdrive auto transmission, you will likely want some lower gearing that is how you get it.
If you have a dana 61 with 3.33 or higher gear ratio all you need is a 5/16 ring gear spacer to run 4.56's and up.
If you have a dana 61 with 3.07 gears and you want to go to 4.56 or numerically higher gear ratio you will need to purchase a dana 61 3.33 and up carrier part# 706400x and a 5/16 ring gear spacer to achieve the desired offset. Or have a 5/8 ring gear spacer custom machined. This is popular for the guys trying to score a cheap front or rear 60's and gear it for offroad use.

(just a guess) but I would measure to be sure.
