Ring & Pinion Gear Sets: 12 bolt 3.73; 10 bolt 3.08
 

As title says, have some rear axle parts I no longer need:

3.08 ratio matched 10 bolt ring and pinion set.
The ring gear has part number 2 GM 1235126 13 40 7 89. Believe this decodes as 13/40 = 3.08 ratio manufactured in July 1989. Did not see a part number on pinion. $40 plus shipping in USPS flat-rate box

3.73 ratio matched 12 bolt ring and pinion set.
The ring gear has part number 3817778 11 41 GM 1 65 1 27. Believe this decodes as 11/41 = 3.73 ratio manufactured in January 1965. Pinion has part number 3864623 GM 2 2 65 11 44, believed to decode as 11/41 = 3.73 ratio manufactured February 1965. $50 plus shipping in USPS flat-rate box

Prices are "or best offer" and these parts are also available for local pickup east of metro Atlanta. Willing to consider trades/partial trades for something of interest for one of my trucks?

Sorry for the delay guys, but the heavy rain earlier in the week damaged the local T1 tower, taking my internet with it till today...

So here are pictures of the 3.73 ring gear and pinion. These were used parts removed some years ago, cleaned off bit, and then put in the box from the gear motive set that replaced them - they do have some dust and grimyness as a result, but I didn't want to clean them since removal of the residue/grime might allow rust to form. For shipping purposes these will be wrapped and boxed in a flat-rate container instead of the foam tray to reduce costs.

Flat-rate shipping costs to the lower 48 states will be $17.80, with optional insurance available for an extra $1.85 making the alternate total of $19.65 insured if you so choose.
