I have a 12 bolt posi carrier that I would like decoded. By the bearing opposite the ring gear casting numbers EDB30174 then 260 or 280 . On the ring gear flange it has J-1-F The gears are dated 6-65 .Are any of these numbers on the carrier a date code or are they not dated thanks.
EDB30174 is a 4 series carrier for 3.90:1 & up gears. I don't know what the 260 or 280 means. Is there anything else on the ring gear like 41 10 which would be for 4.10 gears ???
Yes the gears have 41 10 . What Iam trying to find out if carriers are dated for the model year like the housing are . I was wondering if the 280 is the days of the year or the 28th day of 1970.
