WTB 3.23 rear gear ratio

[VanishingPlymth]

Hi, i'm new here, first post !

I'm looking for a 3.23 rear gear for my 74 cuda. Has a 4.10 in it and i don't like it on the highway which i do a lot. I'm not sure what kind of diff i have, i think its the original one but the gear has been changed. I'm new to e-body mechanical stuff and happy to learn

I have complete 3rd member 3:23 geared differentials. I can ship it.

Unless you know what read you have....
Show us a picture just to be sure it is an 8-3/4.
Also, what size U joint do you have. Not that it is a big deal because the aftermarket still makes a cross over U joint. But, if you have the smaller 7260 joint and a seller has both, he could send you the correct size mating U joint.
It just makes life easier. Even more so should you need to replace the joint later.

If you want to send me some pics of the rear you have and U joint I could send some pics of the 8 3/4 rears I have and make a match for you.
