Rear end identification help
Hello my brother bought a C10 that was a 69. I’m trying to figure out if the rear end is from a 69 or 70 cause I want to do a rear end 5 lug conversion so I want to buy the right kit. NF3896838 GM 58
TPF 0608 W1 Is what I was able to pull off the stamps. Can anyone decode this for me? Posted via Mobile Device |

Looks like you have a 1970 rear end.

Also looks like it is a 3.73 positraction. Does it have the plastic tab on the fill plug? LockDoc
