This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

    I just purchased a rear axle with posi for $100cdn $$ however I cannot identify the gear ratio. It had a tag indicating it came from a 1972 Buick Electra and the axle is 57" +- inside to inside of drum. It has the ss tag and is 12 bolt cover. It measures 9 3/8 +-. I marked the shaft and the axle and rotated it to a little less than 3 turns.

    Markings -
    -I cannot find anything on the axle.

    -It has kinda yellow/orange paint on both the ring gear and pinion

    -the ring gear yellow/orange paint has 3 1 1 hand painted

    -the ring gear has numbers stamped 41814 CN MH 2582 Some numbers are hard to read like the 8 could be a 6, the letters are hard to read too, the N could be an H.

    I also have some stupid questions :Dou:
    1-What is the best gear ratio for performance?
    2-can I swap a 1972 9 3/8 posi into a 1970 riviera axle?

    1. A lot of people love 3.23's They are better on the highway than 3.42's and give you a better launch than 2.93's I like my 2.93's anyway, there is a lot of torque on Buick.

    2. I don't think so.

    Your ring gear has 41 teeth so if you can count the teeth on the pinion you
    can certainly figure it out---12 teeth would give you 3:42,13/3.23 etc---
    when I counted mine it had 16=2.56 :af: now it has new posi and new gears with
    12 :grin: (3:42) Pete
