I'm looking to buy a '77 3/4-ton Dodge 4wd w/ Dana 44 (unit bearing type) & a 203 t'case.....

I would like to convert the 203 to part-time operation (shaft kit) & swap in a Dana 44 HD I have out of a '76 Chevrolet K-20 as is (same ratio).....

Two questions:

1)any problem swapping in the Chevrolet axle as an assembly or would it be possible to swap the outers to gain the selctable hubs?

2)will the 14-bolt in the '76 K-20 work in the Dodge as far as perch width?

I'm unable to measure these mysef right now, away from both trucks.....just trying to get a game plan,

Thanks!
Doc

you can just change from the knuckles uot and your good to go on your 44.

The pearches will be a bit wider I belive on the 14B but not a big deal, cut them off and weld on some new ones.
Have fun

Also the 14 bolt (usually) uses a 1350 U joint compared to the dodge dana 60's 1310. Also, the driveshaft will need to be lengthened about 1" to fir the 14 bolt.

IMHO, the knuckle out swap is the easiest way to go, but you could also bolt in the whole front axle, as the pearches are only .25" off (I have a 10 bolt front in my 77).
Just the brake lines get to be somewhat of a PITA to deal with.

The knuckle out swap would be the easiest. You might need a custom tierod made (narrower axle). Keep the rear D60.

Also the 14 bolt (usually) uses a 1350 U joint compared to the dodge dana 60's 1310.

No, the Dodge uses a Detroit 7260 or 7290. The 1310 and 1330 are spicer joints.

The 14 bolt rear is much stronger, but may not be worth the hassle if you won't need it.
