Can someone help me out here...
1975 Dodge 4X4 duallyI think the truck had a 300 badge on it?
I got the frt & rear axle's, the diff covers look like D60's.....?
But the futher I look these things look bigger than 60's?
Also the rear looks to have some sort of a factory locker, I dont see
any clutch's, or maybe a gear driven L-slip?
They do have 4.88 gears and I do see the #75 on the gears and carrier.
Could or is there even a D75?
Anyone know what I got here?
Thanks
Gene

How about a BOM number or pics, so we can tell you what you've got.

I'm guessing this is the BOM cast into the housing?
Rear C34835
This # is off the rear carrier 5 27 75 B 26703X
And after looking a little harder I found 70 cast into the housing.
Front C37285 along with 60 cast into the housing also
It's a bit beefer than the Ford 60's I'm use to..
Thanks for your time!

Front 60, and rear 70... thats a good setup ya got there.

Front 60, and rear 70... thats a good setup ya got there.

I think your right!
After a little research I come up with a D70 rear with 4.88's and a Power-Lok
The frt would be a kingpin 60 4.88's & disc brakes.
I've had several Ford 60's this set through me off.....
I also found out the 70 & 60 share the same diff cover.
BTW they are for sale $1000 for set like this should be a nice buy!
