Here's what I have found;
I need to id this locker I bought, I got this thing without a box, it is a 35 spline detroit locker but I'm unsure of the application. It has the number 02496 cast into the side, 70568 stamped into the carrier and 67564 7c etched into the end of one of the cross pins. it also has this hand engraved into the carrier:
176
sl29b
70566
16.d.07
70566 is the part number for the case assembly in a Detroit Soft Locker 225SL-29B. If that's what you've got, it's for a Dana 60HD (which is a 35-spline side gear), with gears 4.10 and down.
