1970 CRV 12 bolt posi LS5 LS6 chevelle

[jeremy clark]

Original, unmolested CRV 12 bolt 3.31 posi. I just pulled this from an estate where it had sat on a rack for over 40 years. Guaranteed to not be a restamp. This particular one came from a 70 monte carlo SS with the LS5 engine. You may notice the plates that go on the back of the lower control arm brackets and the extensions for the rubber bumpers that are unique to air shock equipped cars and can be removed for non air shock cars.The Chevelle and Monte Carlo used the same coded axles and the CRV code is specific to 454 cars with 3.31 posi traction. The 454 cars had a larger pinion yoke than 396 cars. The only condition issues are that one of the shock mounts was cut when it was removed back in the day (a 15 minute fix for any competent welder/fabricator) and it is missing one brake drum. Still has it's original "9210" yoke, original gears, original posi, axles, backing plates, upper control arms, brake cables are in good shape. I'm located in Hays, KS and would consider shipping but I'm guessing it would cost $400-500 to go to one of the coasts.
$3,500

Good eye, big gear head, I hadn't noticed that. I could swear this thing has never been a part but I've been wrong before and I'll be wrong again. Think it could have been that way from day one?

[big gear head]

Who knows. I owned a rear end shop for 15 years and I've been building them for about 40 years, so I notice stuff like that pretty quick.

Upon further insection, it has been into at some point. The pinion is dated 10-69 which would be in the right date range and the 3 series carrier is dated G 7 J -July 7, 69. I don't know if that's a reasonable date range for this axle? But the carrier has definitely been removed at some point as evidenced by the replacement shims on the passenger side of the carrier. Still a nice rear, it's just been into at some point in it's life. Sorry for any misrepresentation, honest mistake

It could have also come out of an LS5/6 El Camino with those shock guards & bump stops.
