Will any 10 bolt 8.5 posi unit fit our trucks? For example there is a unit that came out of a SS impala that has a 8.5 10 bolt, will that fit? Also I have seen them off of some caprice cars and and older muscle cars. Someone please help!

 

If it is a 10 bolt ...8.5 it should fit with no problem...Just check and make sure it is the same spline axles

 

what spline axles do we have?

 

Hey man I got the stepsides today. I hope you got the money order too. I did a lot of research before I bought my Eaton and you will need 30 spline axles. Nothing else will work. Hope this helps.

 

yeah I got it today also! Thanx I hope they are what you were expecting!
