I have a 97 F250 HD that I am swapping from the twin I-beam to a solid axle truck. I picked up what are supposed to be the front axle from an 02 F250 and a take out 03 F250 rear. Theaxle tags are as follows.
front: top row: 3.73 (space) a delta/upside down triangle 3C34 (space) FC
botom row 611337-1
rear: top row: 3 (space) V (space) 457 (space) A
bottom: 3L73 (space) 10 (space) 5 (space) 4K21
Any help figuring out what these are/are from would be great. I'm looking at possibly putting air/electric lockers in them, so I need to know exactly what they are first.
