    A friend wants to change out his 3.64 gears on a 70 stage 1 and go with a 3.23 ratio. Unless you use spacers I assume that this requires a change in the carrier. 3.23 was the standard ratio for a 70 GS 350.

    Depending on condition & price of the 8.2 3:64's I'd be interested in a spare set if available.

    I know in my collection I have a new in the box 3:42 ring & pinion but pretty sure they are only for the 8.5 unfortunately.

    Hi Jim,don't know if your friend can wait ,just got a 70 GS 350,don't know if the rear is 8.2 or 8.5.I also do not know the size of the gears and I don't have to tell you that its cold in here,so if he is in a hurry,forget about it.Bruno.

    My GS 350 had a 3:23 rear. Non-AC Auto.

    John- —no interest in selling his 3.64 rear.

    Bruno—yes he can wait. Keep us in mind.

    Good choice IMHO. I'm sporting 3.23's in my Wagon and they are great.
    Had them in the 70 Stage 1 4-speed for a while but now back to the original 3.64 gears.
