Will a 1/2 ton front axle from an AD work on my truck. And do I need anything more than the axle, hubs, spindles, and backing plates. I am trying to keep it pretty much old school. Want to start looking around here first (central/southern Indiana) so shipping won't eat me up.

Also, try to get all the steering gear with the 1/2T axle, as the holes for the steering arms may be different. And the brakes are different.... unless you plan to change to disks in front....
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.

They're about 6 miles north of Terre Haute on 63. very large yard and heavy on older iron. I don't recall seeing any 1/2 ton ADs the last time I was there, but there could be one back there. Be prepared to clim, though, as most of the good stuff (read old) is up at the top of the hill. Nice loooong climb, too.
