My 36' Chevy Master Deluxe, has a 10-bolt GM differential under it,
Drum brakes
10 Bolt,
on the forward side of the passenger side axle housing, there are the following stamped into it ' P.E. G304 1' this information is about midway between the Pinion housing and the drum brake backplate, passenger side.
On the passenger side of the pinion housing, there are these characters: GM23 which appear UPSIDE Down .
On the driver side of the pinion housing, there are these characters. I 2 9 8 along with a date clock, see picture DSC0093.jpg
On the pinion housing, closest to the Pinion nut itself, is these number:
1 2 5 4 3 3 3
The bottom of the casting for the pinion ring housing has squared off corners on both bottom left and bottom right.
The housing vent is located on the top of the pinion housing on the passenger side of the car, closest to where the axle housing meets the pinion housing.
The Pinion nut itself looks to be 1.1/4"
I will attempt to upload pictures,
Can someone Identify the possible year of the casting, the possible gear ratio (consider as if it has never been changed up or down).
If it is posi, limited, or open, and from what type of vehicle it may have come out of.
This is the rear differential that was under the car when I purchased it, previous owner deceased, therefore no answers from him.
Thanks in advance.
