I'm trying to figure change out the rear end?

Hi,

This is a somewhat big job. However, if you take your time, you should be fine.

The rear axle/differential assembly could be one of three different assemblies. I attached the directions below for the 9.75" differential which is the most common.

Take a look through the directions and let me know if they help. Also, if you know that the differential is other than the one I mentioned, let me know.

Take care,

Joe
