I bought a 1957 Chevy 3100 that was converted to a 4x4 a little while ago and have been having trouble identifying the axles. I have tried to do as much research as possible about this but haven't been able to figure out what vehicle these axles came from. The front axle is a Dana 44 and the rear is an Eaton HO52. I found some numbers on the 44 but none appear to be the BOM number and I can't find much at all on the rear. The front has "44 5F" on the front bottom right of the center section. The only numbers I found on the tubes are two series of numbers. The first is "11 7 3 C" and the second appears to be "N73A32657" but the fifth digit (3) is very hard to see and could be a 5. I havent found any identification on the rear, may be looking in the wrong places. I have spent most of my time trying to ID the front because i need to get the proper tie rod and new tie rod ends. When I bought the truck the guy told me he thought the whole drive train was from a 1963 K20 but was not sure. I am trying to verify what vehicle and year they came from so I can get brakes, tie rod, tie rod ends and whatever else I may need. The transmission is a Muncie SM465 and the transfer case is an NP 202 if that helps at all.

Information obtained so far:
-Front
Danna 44
Closed Knuckle
Springs over axle
Passenger side drop
Low pinion
65.5 inches WMS-WMS
Spring perches are almost 2.5 inches wide
Almost 33 inches from center of spring perch to center of spring perch
2x12 brakes
8 lugs
Wheel studs are 1/2 - 20 threads with a 19/32 (0.594) knurl

-Rear
Eaton HO52
Approximately 63 inches WMS-WMS (measured with wheels on so this is not exact)
8 lug
1/2-20 wheel studs

From what I have found through my research, the front seems to match a front Dana 44 from a 3/4 ton Jeep Truck (1963-1973) although i thought jeeps were spring under axle. The rear seems to be out of a chevrolet. Can anyone verify this as being correct or wrong or provide any further information? I cant find any information about a Chevrolet with a front Dana 44 narrower than about 69 inches.
