Have what appears to be an NOS(?) ring and pinion set for "O" rear.... and a pretty rare one...
If it's not NOS, you can't really tell it... may as well be NOS, factory lapped only... it's nice and shows no real sign of use.

It's a 4.66 (4.67) ratio for the '67-70 Olds "O" rear (12-bolt cover, 10-bolt ring gear)... this is factory race car stuff, and was available as a dealer-installed option.

Included in the old GM box is:

--ring gear
--pinion gear with bearing installed
--bearing race in a box
--crush sleeve
--shim
--ring gear bolts
--Oldsmobile Division sheet # 405278, which states: "Dealer Installed Performance Rear Axle Gear Package (For F-85 Series) 4.66 Ratio (42:9)"

The paper sheet and the old GM box are falling apart now, but the sheet is still very readable with a bunch of codes and info. The sheet refers to the 1969 service manual, so I guess this one was made in '69.

OK, well.... that's what I have here. Pretty rare Oldsmobile factory/dealer race car item.

Asking $350 plus Priority Mail.

BTTT...
Pretty certain it's just factory lapped NOS, it's in an old blue-letter GM box, the crush sleeve has never been crushed, the bearing race is NOS Bower in the original box...

I have seen USED 4.66's sell for $300 without the other extras the very few times they've even come up for sale. Nobody needs this?

NOS gears were never "lapped in on the gear teeth" from the factory. I have never seen a set of NOS GM gears like that in my life and I have owned many sets.
