3.73 and 4.10 GM gears - F-Body Road Racing and Autocross Forums

I have 2 sets of gears for sale for our 7.625" 10 bolt axles. They are both GM gears for a 3 series diff.
Gear Pics

The 3.73 is new and never installed. $150 + shipping. This gear is on the left side of the picture. sold!

The 4.10 was installed once but never ran. There is some handling damage to one of the pinion teeth, as can be seen in the picture, but won't be a problem if a correct pattern is used. $100 + shipping. The pic below is a couple months old so it doesn't show the rust.
4.10 damage

Both gear sets have some surface rust from sitting in my garage for the past couple months. I don't think it will cause any problems with performance. The 4.10 is a little worse than the 3.73. I used some 400 grit and it cleaned right up.

I accept paypal.

Thanks
