Tell me about my Dana 70 Rearend

I have a 69 f350 crew cab 2wd. The axle code is 27 which indicates dana 70 with 4.10 gears. The guy i bought the truck from said that is a positive traction rearend that is sought after because of the quick change gears. I want to make the truck 4 x 4 and i want to up the ratio to 3.54 in the rearend for a DD. the 4wd part is just to stay out of a bind. I don't and won't be mudding the truck. I know little about 4 x 4 stuff. I do know i will need a np 205 divorced transfer case to make the swap. I have a neighbor that has a 70's international scout that has a transfer case i can get from him cheap if it will work? Any advice?

It is very hard to convert to 4wd as the frames are vastly different. You have a big honking crossmember that is in the way. Your choice of IH tc means you would have to pick a Chevy or Dodge axle as it has a right drop compared to a Ford tc. A Dana 70 doesn't have quick change gears as you would have to spread the case to get the gears out compared to the 9 inch. The 9 inch is known as the poorman's quickchange.

Thanks Rich, like i said, i'm in the dark on the 4x4 stuff. I do plan on doing my homework. I may hold off on the 4x4 aspect of it all. I'm gonna have to rebuild the crossmember for the the 5.9 anyway. I just don't wan to have to do it twice if i can go 4x4. What other frame differences will i encounter? Somone has suggested the crewcabs came on the highboy frame. How can i tell?

1959 thru today: If the AXLE code begins with a letter: Limited Slip. If with a number: No Limited Slip.

27 = Dana 70 Rear Axle / 4.10-1 / non Limited Slip / 7,400 lb. Rear Axle Capacity.

So does that mean it is a positive traction rearend?

Tell me what i have there? BTW it is not listed as the limited slip in the chart. Does that mean a positive traction?

No, it does not.
Posi, Positraction & Positive Traction are GM terms. Ford: Equa-Lok and Traction-Lok = Commonly referred to as Limited Slip.

Since the AXLE code begins w/a number: No Limited Slip.

38 = Dana 60 Rear Axle / 3.73-1 / non Limited Slip / 5,200 lb. Rear Axle Capacity.
------------------------------------------------------------------------------
1968/72 F100/350: There are two types of A/C, factory & dealer installed. Both are "hang-on" units, bolt to the bottom of the dash.

1) Factory installed Integral A/C is combined with the heater, the A/C controls are in the same panel as the heater controls.

There are two glove boxes. Since the A/C's expansion valve mounts where the glove box liner is, it's present, but is much shallower.

There is another glove box within the A/C's bezel.

2) Dealer installed A/C is not combined with the heater. The A/C controls are mounted in the bezel.
------------------------------------------------------------------------------------------------
Peeps confuse 1968/72 A/C's with 1973/79 in-dash A/C's because of the separate glove box issue.

1973/79 F100/350: There are three types of A/C: Factory installed Integral A/C, Deluxe Dealer installed A/C (combined w/the heater) and Economy dealer installed A/C (not combined w/the heater).

1) Factory installed Integral A/C is combined w/the heater, the A/C controls are in the same panel as the heater controls.

2) Deluxe Dealer installed A/C: The A/C controls are in the HUGE dash bezel that sweeps across the entire right side of the dash, covers up the original glove box.

There is a separate "hang-on" glovebox bolted to the bottom of the dash.

3) Economy Dealer installed A/C is not combined w/the heater. The A/C controls are mounted into a panel that also contains two registers.

This panel mounts into the dash, to the left of the existing glove box.

thanks for the info, i hope to go get the 72 f250 soon so i can see what all i can use off of it. I thought i had disc brakes on my 69, but no luck there. I'm hopeing the 72 does. . I'm still not sure that the 3.73 would get me where i wanted to be with the load RPM of the cummins. The OD may make the 3.73 just the ticket. I'll have to see. I am also assuming since it is a no-slip rearend, it pulls with both wheels full time.

Dual piston caliper front disc brakes were an extra cost option on: 1968/72 F250 2WD's and F350's, so not all these trucks had disc brakes.

I may not be able to get it all done on my budget, but i would like to a least get a dana 60 and power steering in place. My truck has drum brakes on the front so it would seem necessary to kill two birds with one stone by swapping to disc brakes with a dana 60. I could just get the hub components and swap later, but it seems too redundant.

NumberDummy could you give me any insight on this:

Would you be able to answer this question for me: I have looked everywhere and talked to serveral people, without getting a solid answer. I am rebuilding a 79' dana 60 kingpin axle. I bought a kingpin rebuild kit, but it did not come with upper kingpin cap bolts. I can't find them anywhere, Spicer stopped making them and I cannot find just the bolts anywhere for sale. So, I am ready to go to the hardware store and get some. I know that they are 1/2"-20. What I do not know is the length. One guy said that he thought that they were 1 1/2 or 1 3/4. Do you know? And are they different lengths on the left side verses the right? Thanks Bill.

I think a specialty fastener place like Fastenall would be your best bet. Take one of your old ones in. You probably won't find them at a hardware store, anything with enough shoulder will be too long.
That being said, I have made them in a pinch but that was a looong time ago. Just get a longer grade 8 bolt, cut it to length and cut the threads down to the right place.
