I know this has been covered several times so I did a couple searches and got most of the information I needed. Just a few other questions to those who have done the swap. I have the opportunity to buy the axles out of a 86 grand waggoneer. The front is a dana 44 the rear is a amc 20. I also have the opportunity to pick up a semi float corporate 14 bolt with the 6 lug pattern to use instead of the 20. Anyone know if they will be the same width WMS or should I use the 20. I know I need to swap out the drive flanges on the 44 for warn internal hubs. I have not yet seen the 44 axle, what kind of brake set up am I looking at. The searches imply that anything later than 70s should be disc :). Do I need any special lines, or should I use chevy or ford brake parts on it? Anything weird that I'm going to run into with the front?
From what I've read only the earlier waggy axles had flat top knuckles :(. I also read I could convert to ford parts to get 5 on 5 1/2 pattern with flat top knuckles, the chevy stuff should work then to run 6 lug correct?

The semi float 14 bolt will be way wider than the Model 20, I'd use the 20 for now, but keep your eye out for a later Waggy Dana 44 rear, post AMC ('87) Waggies should have them. The Dana 44 will have Chevy style disk brakes, so you can use standard lines, and if you're cool with 6-lug, then they will be fine, if you want 5 on 5.5, that's easy too. You can swap early Jeep or Chevy flat-top kuckles on at anytime, they are a direct replacement.

If you want big rear axle beef, you can slap some eight lug Chevy hubs on your Waggy front, and run a 14-bolt full floater from a Cab and Chassis dually or work box type dually, any dually without a standard pickup box and the big bulging fenders, they are approx 60" wide, same as the Waggy model 20

i wouldnt waste time going from a amc20 rear to a d44.. they are about the same in comparison.. dana lovers really hate that statement..

i cant answer on that width question.. depends on what the axle came out of.. i have seen semi floaters in cab n chassis trucks.. and those are the rear axles that are the right width.. also check out motor homes.. delivery trucks.. anything that doesnt have the wide duallie tires on them..

and yes.. the brakes will bolt right up to your stock lines.. the older brakes.. 79 an older disks use a larger banjo bolt.. which you can just drill out your brass coupler to fit the larger bolt thru.. i have a good write up on my site on the flat top knuckles and 5 lug conversion.. you can use the 8 lug hubs for that bolt pattern..

but i would just put both axles in it.. and be done with it.. till you can find a good rear.. then just convert the front to 8 lug.. or upgrade it..

I doubt that statement highly. The semi-floaters were only used in the light 3/4 ton version of the pickups and some 1/2 tons. Any cab and chassis is going to have a full floater which are 63" wide.

As for the width the 14 bolt is probably about 67" wide. Depends on what year though. The Waggie 44 will be around 62" wide.

Nope grand waggie should be around 59-60" max.

I agree with cmegoup, most of the 14's (non Cab N Chassis) are around 67-69. I've taped what seems like a million of them in the yards lately. The cnc 14 will be 63" -- too wide if you're going to run a 59" up front.

Thanx all, I'm going to pick up the axles. They should work better than what I'm running now.

My front Waggie is 61.75", thus my "around 62" statement. A rear Waggie is around 59-60", but he was looking at a front 44, not a rear.

ditto, mine is an '87 and is just under 62", the rear is about 58.5"

Hmmm, my Waggy front is from an '81, and it measures just a hair over 60" from wms to wms, with Ford hubs and Chevy brakes on it, the 20 rear that came with it was 58.5", same as the Early Bronco 9" in my Jeep, I usually call it around 60" for Waggy's and Wranglers, around 56" for wide CJ's, around 51" for narrow CJ's, around 67" for fullsizes and J-trucks, but they all seem to vary a little

My '80 Waggy 44 front is 62" wide....

How did you combine Ford hubs and Chevy rotors? Redrill the rotors to 5 lug?

You use Ford hubs and rotors with Chevy calipers and caliper mounting plates.

Yes I know how it is normally done. He said he used Ford hubs and CHEVY BRAKES. i was just wondering how/why. I guess I should asume he meant Chevy calipers.
