Axle help

[73EStroker]

Need some verfication of measurements here if anyone can help please.

I have modified a Ford truck 3/4 ton Dana 60 Trac-Loc down to Challenger specs with the Mopar flanges, spring hangers etc to fit my Chally. I will be using custom Moser axles once I can get the measurements to them.

Housing info:
- Flange to flange 56-1/2"
- Drivers side  to pinion center 29-3/4"
- Passener side to pinion center 26-3/4"

Axles Info:
- overall length 29-15/16"
- from spline end to bearing step 27-1/2"
- bearing inside diameter 1.575"
- spline count 30

Also can anyone verfiy that the Ford dana is 30 or 31 spline count. I have no way to see into the diff to count the splines. I want to run the stock bearings and adjusters with the center block installed in the diff.

Thanking you all in advance

Wouldn't they be 35? 

Seems to me the early Dana 60s are 23 spline and the later ones are 35 but I'm using my memory so

360 - I pulled an axle from an early to mid 80's 3/4 ton Ford (couldn't find a 73model) the other day at the same wrecker and it had a 30 spline count So you see the confusion. Maybe it was not a Dana but it sure looked like one. Mine is out of a 73. CP and I took the diff out, when I pulled the axles I just tossed them into the truck not thinking about the spline count. I will most likely pull the carrier this weekend and do the count. Word is that the diff goes straight back in with no realignment needed for a Dana if you don't move shims around etc.

But if anyone can verify the other measurements for me please.

I went on some 4 wheel drive forums and they say you have the 30 spline because the 35 spline is rare except in aftermarket.
