part number help- 12 bolt posi case

[redvetracr]

I have a NOS GM Eaton 12 bolt posi in the GM box, someone covered the part number tag with green painters tape all I can read is gr 5.510 or gr 5.610 "case" and a partial part number 3??9316 can anyone please look in a GM parts book and give me both the whole part number and the description??  the posi is marked EDB-30140 and has side bearings, it might have been a loaded posi someone stole the guts out of...thanks in advance

Group 5.510 shows 3869316 as a 4 series case, Eaton ED30174.
ED30140 (3869315) is a 3 series case.....Joe
