I did try your calculator till I got to the point of measurement A and B that is what I didn’t know.

You don't need to plug in those measurements. Just hit "calculate" after entering data in the first three steps, and it'll populate those fields automatically. After plugging in Dana 60, stock Mopar pinion offset, and stock A-body width, it says "A" should be 20.49" and "B" should be 21.865".

Well there you go, just need to know how to do it. Thanks
 
Sounds like you chose "use existing housing or axles". This option is used only if your housing is already narrowed.

If you are building a rearend with stock dimensions, choose the following prompts:

1. Dana 60
2. Mopar passenger car (1 3/16" pinion offset)
3. Stock A-body
4. Calculate

Did that thanks. I’ll be ordering axles from you when I get to that point. Thanks for your help.
 
I didn't see it mentioned anywhere but what is the original gear ratio on the rear end ? If it is very low like into the 5.00 to 1 or lower, isn't it true that the higher ratios like the 3.54 will not fit the housing?

No that is not true.

If you go below I believe it is 4:30 then you need a different carrier for the ring gear. You still can use the same housing.

Original ratio is 3.54. I also have a set of 4.10

No flashbacks Roy. Tunnel is offset. And when I shortened the 8.8's for my cars we made the axle tubes the same length. Let the pinion fall where it may, should be about right. Assuming that the Dana 60 is about the same. But I have no real experience shortening a Dana 60.

We had a dana 60 shortened by a reputable machine shop , back in the day . It was done so both sides were the same , never had a problem , was behind a 426 hemi , in a heavy *** belevedere , with 14 and 16'' slicks .
 
I'm putting together a 52 5/8 to put in my Duster. I just need some 4.56 gears and then I can finish putting it together.

I have a truck housing that I want to shorten to stock A body width. Now I know a stock A body width is 52 5/8”. But I need help on what the left and right axle tubes should be to have the right center offset. My first attempt at shortening a Dana 60 truck housing. I have a set of 3.54 and 4.10 gears. Still looking for a Track Lok unit. Any help is appreciated.

I have a couple sets of 8.75 axles & they're equal length. I'm pretty sure it's equal tube lengths. The Dana is wider, so put it on the springs, get your driveline so it's square off of the trans & mark where your at. Add on whatever length you need to where your flanges need to be. If you have a laser it should be easy, Mark out center off the yoke with a plumb Bob, find dead center of the output shaft, use a plumb bob, shoot a laser & line the points up.
