Rear Axle ID
76StepSd:
I got a 76 stepside but....the guy i got it from had to replace a number of driveline items...i.e. engine...trans.....rear end..lol. Oh yeah some major replacing went on but i am just trying to find out what rear axle ratio i have. I believe the axle date is August 17 1978 but you can correct me if i am wrong but what was stamped on the tube was
KAS 074W91 that is what i am mainly concerned about. Any info would be greatly appreciated.
Irish_Alley:
ive never really been able to find anything off the stamped numbers. for the most part if you post a picture of the housing then we can tell you what years they came in and for the most part all parts are interchangeable within those years
76StepSd:
Here ya go
76StepSd:
Sorry had to rotate it 90.
Irish_Alley:
alright, well its obvious that its a 12 bolt and the guessing comes from the stamped codes you showed. im finding 3.07 (stock ratio but could be changed) Jb5 brakes and came in the years 78-79 ½ton 4x2 non-locking
