    Last week I bought a parts lot from what was left of a 69 Riviera GS. The rear end I got is a 9 3/8 posi with 3:42 gears. I was wondering what would it be worth? The gears and carrier is what most people are interested in and I know that there is no aftermarket support for these rear ends so these gear sets are really rare and hard to come buy.

    ALL depends on the condition... And the persons want of the parts.
    500.00 to 1000.00 If you do not know anything about it ...condition or history... then lower end. If it was reconditioned unit with its original pieces and your selling it knowing it is all good to go with no issues higher end.

    That is the best guess. AGAIN you could get way more also all depends on how bad someone really wants the parts. :)

    I got $600 for the last 67-70 3.42 9 3/8s rear I sold about 5-6 years ago. I thought it was a fair deal at the time. The 71+ Posi unit I sold 4 years ago was for $350 I think.

    Hope that helps. I have one more 3.42 rear that I don’t plan on parting with anytime soon.

    The whole rear end has never been opened up, it's from a 88,000 mile car that was bought and parted out in 1992. The rear has sat in a shed since 92 and is now in my garage. Judging from the condition of the rest of the parts I got the car was extremely well taken care of. The complete interior I got is in amazing shape. I was told the cars floors were rotted out (probably because it was a Canadian car) and was bought for parts to restore the 68 GS that the gentleman who I bought the parts from still owns. I was thinking of opening up the rear to confirm the actual gearing and condition.

    You should do that and take pictures to sell it. You will ALWAYS get more money that way... UNLESS you stick it into a car and have it running and the customer can drive the rear in the car...THEN that is the best and most efficient way to get the MAX money

    Thanks for your input Jim I appreciate it! I will crack that baby open and confirm what's in there before listing it. I've heard it's really stinky opening up a 50 year old rear end:p:D

    IF the oil is clean with NO metallic particles save it as the "Stinky" oil is the best ever available as far as I'm concerned.

    UPDATE: I started a new thread on this because I forgot about this one I already had going:rolleyes: but the rear gears are indeed 3.42 posi and I was told everything looks good. The oil was the original stinky oil with no metallic particles in it so that's a good sign!:)
