rear axle decode

can anyone decode these axle numbers for me?. i have found TDE 0822 W2 and GM54 and NF3896838. the old chevy truck i have may have had a transplant rear end. any help you can give would be greatly appreciated.

 

Hey rxmolina, what year model is your truck? That will narrow the search a little.

 

the truck that has the rear end is a 1965 1/2 ton.

 

i think i got you fixed up here. TDE was a rear axle designation for a 1970 1/2 ton with 3.07 to 1 gear ratio.

 

thank you so much. i appreciate your help!
