I will the Posi fit a 10 bolt in a 72 chevelle?

 

[crazy427]

Only if you have a 8.5 with 30 spline axles. I believe a 72 chevelle may still have the 8.2 10 bolt and would have 28 spline axles.

Thanks

Im not sure about the starting point for 30 spline rear axles in the rear differential. i know that they didnt start using 30 spline in the front till late 89 and on

i wont be able to pull the axle and check for a week or so, if they are still available i will pull it and check......thanks!
