I have a posi unit that i removed from a camaro 10 bolt rear end.The casting number is 410406N.I cannot find any info on this center section.Anybody know what this fits or what gears will work on it.Thanks

Could your 6 actually be an 8? I found on nastyz site something close. It was 410408N which was a 3 series 8.5 2.73 & up rear.

This is a Traction Lock from the 8.5 10 bolt. There are only 2 versions. The 2 series is 410409 and the 3 series is 410408. Look at your casting number again and see if the last number is a 8 or 9. There is no 6. The 4 large number on the same endf of the case will be the same as the last number of the casting number.
