I may be wrong but I believe that big 9 cast up on the housing there tells you that it's a 489 housing also.
Look on ring gear and sure grip parts.Do they have a date code any place?
Must have been Friday last shift!. Odd how they left the 9 off of some of them
Also 57-64 were 657 (same as 741) and 985 (same as 742).
What do you mean?And thanks for helping me to resolve my bad on my gear change! Not all centers and cases are compatible!
What do you mean?
The 742 case with 489 center dropping from 4.56 to 3.55, and pinion hitting the center remember?
I thought you could mix n match pumpkins between 8 3/4's??
Good to know if not.
