I have some 28 spline axles from a 68 Chevrolet that measure 29 5/8 from the end of the shaft to the face of the hub where the studs are. Will these work in my 83 camaro with 7.5 10 bolt? I have a 28 spline posi carrier that I want to put in.

 

No

 

The 29 5/8 axles will fit a 8.2 10 bolt Chevy rear end in a '67 to '69 Camaro, '68 to '71 Nova and a '64 to '67 Chevelle. They will be too short for your Camaro.
