Tyme55,

As Napco Man mentioned, a Dana44 front axle should bolt right up to your original front springs, you will just need to get 3 new U-bolts made up, as well as a couple of Grade-8 bolts of the correct length (you may also need to make up some plates to bolt everything together).

As far as the rear axle, get some 4" Lift Blocks and some longer U-Bolts and you`re done. Just make sure the gear ratio is the same for both axles. If you get a matching axle from a donor truck, you will probably have to move the spring perches in a little. Nothing to terribly hard, just a bunch of grinding and welding required.

I`ve got a Dana 60 front and Dana 70 rear under my `59 3800 (One-Ton) Longbox. Pics start here: http://good-times.webshots.com/album/562816192hotBxO?start=36
