I posted in the wrong section so I have move over to you guys. I bought a 9" rear end caked in grease and road film. I payed $125.00 for the rear end and on the way home I payed the local car wash a visit. I got the tag all cleaned up and from the numbers my guess is it has 3.25 gears and I think it has a locker. I was told it came out of a 1971 Ford ranger pick up. I am putting it in my 1969 pick up. I will post pictures of the rear end. This is as clean as it got after $5.00 in the car wash. Hope the pictures help.
you are right about it does not have a locker. I did find that fordification site. I did learn something about this rearend. The WDM-S was from 63 to 72 and the owner told me it came from a 1971 truck so that I am pretty sure is correct. the 9LA on the tag I could not find anything on that other than the made a NL and L version which I dont know what that means. I did see where it is a 3.25 ratio and 28 splines but that is all I know so far. I will be installing a Detroit Locker in this rear end so I dont have trouble pulling my bass boat up the ramp since trucks are so light on the rear end. Thank you for the help with this unit.
